Design and Implementation of Single Leg Dual Output Inverter

In this paper, two single phase ac loads are supplied with one inverter and reduced switch count topologies are introduced in this paper. It has three switch single leg structures. This single leg inverter is functionally comparable to half bridge inverter working independently though with a less number of semiconductor switch and hence control and gate drive circuit components. This three switch topologies has two modes of operation which are equal frequency (EF) and different frequency (DF). Each modes of operation has its own distinctive characteristics are considered for them and their PWM schemes are elaborated. Comprehensive analysis of power loss profile and output waveform properties are conducted via simulation and their result is compared with half bridge
