R3 DC/DC Converter for Photovoltaic Inverter Application

The alternating current can be converted to direct current via the inverter system that consists of inverter bridge, control logic circuit and filters. Photovoltaic inverters are widely used in three-phrase grid-connecting.

URB2412LD-20WR3 privodes power to the IGBT drive circuits and the IGBTs convert  DC to AC by its switching on/off operation.

Above shows the three-phrase inverter system. The system can work as single phrase  inverter system when there are only 4 ways of IGBTs.
