Solar Inverter Design

Figure 1: Replacing a SJ with a SiC MOSFET, switching loss decreases significantly

Due to the ever-increasing demand for a clean and renewable source of energy, installing solar systems has accelerated significantly in the last decade. Contemporary solar applications require very highly efficient, power-dense and lightweight grid-tied inverters. Traditionally, IGBT has been the device of

1.5kW Digital Totem Pole PFC Design for Air-Conditioner Using iMOTION Digital Controller

Figure 1: Simplified hardware diagram

A lot of research focuses on bridgeless PFC in order to achieve higher system efficiency compared to traditional boost PFC. Most of the bridgeless PFC solutions suffer from EMI issues, which cause problems in applications where an  inverter stage shares the same ground. In this case, the PFC stage generates
