DUAL BUCK INVERTER FOR WIND AND SOLAR POWER GENERATION WITH SERIES CONNECTED DIODES AND SINGLE INDUCTOR

Abstract

In this project presents a DC-AC system, some problems may threaten the
reliability of the whole system, such as the shoot through issue and the failure of
reverse recovery. Some methods are proposed to improve the reliability of the
converters. The dual buck inverters can solve the above problems without adding
dead time but the dual buck topology has a main drawback of low magnetic utilization
which increases the volume and weight of the system. This paper firstly summarizes
the traditional dual buck topologies including a kind of single inductor dual buck
inverter which can make full use of the inductance. Then a method to improve the
reliability of the MOSFET inverter is proposed.
