Tired of AC loss calculation? We measured them for you! Try the REDEXPERT and calculate your losses in real-time.
Have a look at the different features
The AC Loss Calculation
- Based on real time application set-ups and measurements
- AC loss is caused by flux swing with respect to time in core and windings
- DC loss is the copper loss in the windings
- A pulsating input voltage is applied over the inductor
- The input and output power is measured
- (Pin-Pout) is the power loss in the inductor
- This process is repeated over a wide range of parameters including variation of peak flux density swing to produce own empirical data
Scope shoot of power loss measurement
- PAC = ʃ(∆I, freq,DC,k1,k2)
- Accurate calculation of losses for any given duty cycle
- Accurate over a wide range of frequency (10 kHz to 10 MHz)
- Considers even small changes in core material and winding structure
- Valid for components with more than one material
- Accurately estimates losses of iron powder and metal alloy materials
- Valid for any shape and structure
- Includes AC winding losses
- Constantly improving and adding new data, based on customer feedback
The DC/DC Topology Calculation Tool
- BUCK
- BOOST
- SEPIC
- AC losses (Core and AC-Resistance)
- DC losses (I2R)
The Table
- Sort by different filters
- Set filters are shown above the table
- Filters are set by drop down or by the DC/DC topology tool
The Storage Bar
- Drag & drop from the table into storage bar
- Drag & drop to remove articles from the storage bar
- Colors in storage bar and graph show the same article
- Grey marked articles are former chosen components which got obsolete through new calculation and/or new set filters
- Order button adds components to the shopping cart for free samples
- Share button (social media & short URL)
The Graphs
- Zoom in and out right at the top corner
- Articles are (de-) selectable
- Show each value along the measurement curve
- Current pointer (x-axis value from table)
