Large commercial and central utility power generation systems are the fastest growing sector of the PV industry today. Growth is spurred by continued reduction in the price of PV electricity and by favorable government policies, including feed-in tariffs, tax incentives and the requirement for utilities to provide a certain minimum percentage of their power from renewable sources. These systems can range from tens of kilowatts for commercial rooftop systems to over 100 megawatts for utility-scale central power generation plants occupying many acres of land. The inverters for these systems are central inverters, although a parallel combination of several string inverters may also be used. In addition to supplying AC power to the grid, central inverters may also be used for power factor correction.

Implement Efficient Solar Inverters Using Freescale Microcontrollers and Digital Signal Controllers
The efficient transformation of solar energy into electricity for home usage requires smart battery management and DC/AC voltage conversion, requiring electronic circuits to be precise, robust and interconnected.
Join us on this session to understand how low-power high-performance Freescale MCUs and DSCs can manage trivial tasks in solar inverter systems improving efficiency, reducing noise, and allowing system supervision among many other things
Energy Regeneration
When we talk about energy conservation, what are some of the things that come to mind? Maybe the responsible use of energy? A more efficient load or energy delivery systems? But what about reusing energy that has already delivered to a load and stored as kinetic energy. Some examples of these might include a rotating inertial load connected to a motor shaft or passenger vehicle decelerating. All of these systems, posses valuable energy which, until recently has simply being discarded in many cases.
With the current costs of energy, it is necessary to use and reuse energy as wisely as possible. In this presentation we will review and explore various topologies and control techniques to recapture load energy, in such a way that it can be used by another system, or stored for later use
