A New Three-Stage Buck in Buck, Boost in Boost Grid-Tied Inverter

چکیده
A new kind of buck in buck, boost in boost grid tied inverter is analysed in this paper. In this family of inverters only a single power stage works at high frequency at a time. This reduces the losses due to switching and hence improves efficiency. There is only minimum filtering inductance in the power loop and over filtering does not take place. The analysis of the operating modes of the inverter is done through the equivalent circuits of various stages in a half-bridge configuration of the inverter. The closed-loop simulation of a 230V/50 Hz, 2kW is included.
