Keywords:demonstration board? solar applications? power?

This application note describes the modifications implemented on the STEVALISF001V1 demonstration board, originally designed to work as a PFC rated for a power of 3kW, to be used as a front-end boost stage for photovoltaic apps.

In recent years, the field of solar energy, the production of electric power using solar cells, is requiring power electronic solutions to manage the power delivered by the panels. The DC voltage provided by the photovoltaic field needs, in many cases, to be boosted before supplying a second electronic power stage needed to convert the DC source into AC voltage, required by domestic appliances or for grid connection.

The power conversion must be done with a solution capable of working at high efficiency to avoid energy waste. Each and every watt is important. The availability of new power devices with lower voltage drop and higher switching capability allows a very efficient solution to be obtained, wasting only a few watts while managing power in the range of thousands of watts.
