A non-linear load is one that does not behave like an ideal resistor, in that the current drawn from the power supply is not proportional to voltage and/or the initial currents are often much higher than the rating of the power supply. These loads can cause problems for power supplies, but are actually present in many applications: Large switched capacitor banks Point of Load DC-DC converters Thermal printers DC motors The main issue from a power supply’s point of view is that the load can activate the internal over-current protection. Over-current protection (OCP) is an essential feature for a power supply, but the power supply is usually expected to recover automatically with no manual intervention. So to start with, let’s look at the types of OCP. There are several basic methods used: Constant Current Fold Back Fold Forward Hiccup Constant Current When an overload condition occurs, the output voltage falls but the output current remains at a fixed level. This type of protection is not well suited for delivering peak loads as it can lead to the power supply latching. Fold back When the current drawn reaches the OCP limit, the voltage falls, but this time the current decreases as the overload gets heavier. Again this type of protection is not well suited for delivering peak loads as it can result in the power supply latching. Fold forward When the current drawn reaches the OCP limit, the voltage falls. This time the output current increases to a set maximum at short circuit. Fold forward is well suited for powering up motors, but requires heavier system load cabling to handle the additional overload current. Hiccup At the OCP limit, the power supply turns off for a short interval and then automatically tries to restart. Hiccup mode reduces the need for heavy cabling or pcb traces, and this type of protection can be modified to deliver a peak load. With traditional Analog Control though, the OCP points and recovery timing are fixed. With Digital Control we can use software settings to adjust the limits and timing; for example we can set: 10s for an initial overload condition 60ms for heavy overloads 5ms for a short circuit condition with recovery times or 1 to 2 seconds Let’s take an application example of a discharged capacitor bank being switched onto an operating power supply with Analog control. The lower (blue) trace is the power supply current; restarting twice with the power supply current limit set at around 60A. The top (gold) trace shows the output eventually recovering, but tolerances with the hiccup mode timing could have prevented a full recovery. This time the same discharged capacitor bank is switched into a TDK-Lambda CFE400M supply incorporating digital control. The blue trace is the current, gold trace is the output voltage Using Digital Control, we can set the thresholds and timing accurately. 50A for 1.5ms (The short circuit condition) 30A for 50ms (The over current condition) Notice that there are no multiple attempts to recover after the capacitor bank is applied to the power supply. To summarize: Digital control can allow for precise and repeatable current limiting using load dependant timing. We are not restricted to the value of a timing capacitor which can change due to: a) Batch tolerances b) Aging of the capacitor c) Capacitor values changing with temperature Digital control allows for easy tailoring for different applications with no physical modification of the power supply is needed. All changes are handled with software programming!power_suppliesdigital_controlconstant_currentnon-linear_loadshttps://community.element14.com/products/manufacturers/tdk/w/documents/17014/low-voltage-models-added-to-zws300baf-seriesFri, 08 Oct 2021 07:52:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:f12b83a3-95b0-498e-ad0b-7e4d51ad5908NortskiTDK Corporation introduces the addition of 12V and 15V models to its TDK-Lambda ZWS300BAF series of high reliability power supplies.

Usually the power supply in question is an open frame type , which does not have the shielding that a metal enclosed power supply has. There are two areas that are worth checking; grounding points and wire harnesses. 1. Grounding Points Power supplies utilize decoupling capacitors; two are typically connected from input to earth ground (see below). Likewise, two are connected from the output to earth ground. This keeps the noise currents circulating close to the power supply, rather than allowing them to radiate around the end user’s system. In an enclosed power supply these capacitors will be grounded through the metal case, but with an open frame type, it is up to the user to connect these points to ground. With the power density of products today, there often is more than one point on the power supply printed circuit board that needs to be connected. A common mistake is to only connect one, which can cause excessive radiated and conducted noise. The installation manual will show which mounting holes / points need to be grounded. In the product below, three mounts should be connected (A, B & C). The photo below shows the same power supply undergoing EMC testing, and it can be noted that the unit is connected to a metal plate with metal standoffs. A quick glance of the underside of the printed circuit board will show which mounting holes have traces that need to be grounded. This smaller model has only one grounding point at the bottom right hand side of the board. 2. Wiring harnesses In the test photo, it can be seen that the cable harnesses are neatly dressed and are kept away from the power supply. Wiring that is positioned above or below the unit will pick up radiated noise, thus defeating the purpose of having the EMI filter components. If I am assisting customers on site, I always pack some tie-wraps in my tool kit to re-route any offending harnesses. An earlier blog covers the standards http://power-topics.blogspot.com/2007/11/guide-to-emc-standards-for-power.htmlradiated_emiwiring_harnessesemigrounding_pointspower_supplyconductedhttps://community.element14.com/products/manufacturers/tdk/w/documents/16913/what-makes-switching-power-supplies-hissFri, 08 Oct 2021 07:50:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:f8e5e2bb-6f8b-4b17-8ab6-1e185dc69fc3NortskiI attended a technical briefing two years ago given by one of our Product Managers on TDK-Lambda’s 400W CFE series, and was shown the various ways the product could potentially reduce internal energy losses - particularly at very light loads – using features available from the power supply’s digital control circuits. He did say that there were a couple of small side effects if all the features were enabled. Recently one of our salespeople emailed me stating that in an off-load condition, his customer could hear a 10 kHz hissing sound coming from one of our 60W output power supplies and was curious if the unit was faulty. Normally I would have asked about capacitive loading conditions or if the product was being grounded correctly. Remembering the briefing I checked the product specification for no-load power draw. Seeing that it was a low 200mW, I talked to one of our Design Engineers. Before Energy Star legislation came into force, power supplies would often draw 5, 10 or even 20 Watts when in a no-load condition. Apparently this was accounting for about four percent of the total electricity used in the US. Now most small power supplies will draw less than 300mW. Although the legislation is aimed at consumer products like phone chargers, many industrial customers are now requesting similar energy saving products. I was informed that many of the new power supply control chips employ advanced energy saving features, and what my customer was hearing was probably the converter going into “burst-mode”. AC-DC power supplies above 70W will often have two converters in them; one is the boost PFC (power factor correction) converter which ensures that the input current is not drawn in big “gulps”, but more sinusoidal like the applied AC voltage. An interleaved PFC converter shown below is used for this purpose. The other is the main switching converter which chops up the high voltage DC from the PFC section and provides isolation, voltage step down regulation and filtering. A commonly used “half bridge” circuit is shown below. Back to the subject of hissing! Without energy saving modes, both of these converters run continuously, regardless of the applied load. Each time the FETs switch, energy is used by the gate drive circuits and lost in parasitic inductance and capacitance. To avoid this, designers of control ICs have implemented features where the power supply engineer can have the PFC converter, the main converter, or both converters turn off for short periods of time, aka “burst-mode”or pulse skipping, during light loading. This means that instead of the FETs being turned on every 10us for a power supply operating at 100 kHz, the FETs will be switched on for a few cycles say every 100us. This is enough time to replenish the internal capacitors with energy and keep the output voltage in regulation. The upside is much less power is dissipated in the power supply, but the downside is that instead of the product operating at 100 kHz (well above the human hearing range) a faint hissing might be audible as the burst mode operation operates at 10 kHz. If the energy saving feature of the control IC is fully maximized, whereby a much longer interval between bursts is enabled, an increase in output ripple may be also observed. Often this is acceptable to the end user provided that the output voltage remains regulated. My suggestion to the salesperson was to offer our customer an alternative power supply that had a slightly higher off load power draw, but no burst-mode operation. That suggestion was accepted.drawswitching_power_supplyhissloadhttps://community.element14.com/products/manufacturers/tdk/w/documents/16925/quarter-brick-dc-dc-converters-have-a-200-425vdc-inputFri, 08 Oct 2021 07:50:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:fd180f53-7371-432b-8913-60a03cd04962NortskiTDK Corporation announces the introduction of the TDK-Lambda PH-A280 series of DC-DC power modules with high voltage DC input. These quarter-brick modules operate from a wide range DC input of 200 to 425VDC, which is widely used in HVDC (High Voltage DC Current) and solar cell related applications. The PH-A280 power modules are available in four output power levels of 50W, 75W, 100W and 150W. Nominal output voltages consist of 5V, 12V, 24V or 48Vdc; adjustable by -20% to +10% (+/-20% for 5V output models). Efficiencies of up to 90% are achieved, an improvement of 5% over the prior series. The modules can operate at full load over a wide baseplate temperature range of -40 to +100°C making them suitable for liquid, air cooled or conduction cooled systems. The dimensions follow the industry standard quarter brick format (37.2 x 12.7 x 58.3mm). As standard, the PH-A280 units are equipped with remote sense, remote on/off, overvoltage and overcurrent protection circuitry and include TDK-Lambda’s 5-year warranty. All models have an input-to-output isolation of 3kVAC, are safety-approved to UL/CSA/EN60950-1 and carry the CE mark in accordance with the LV Directive.
