Abstract :
In this paper, a new isolated DC-AC converter with “sinusoidal shape” output voltage is analyzed, simulated and verified with a scaled prototype. Design expressions for selection of passive component values and design requirements of power semiconductor devices are given. The control algorithm is thoroughly investigated. The converter losses based on the commercially available semiconductors are calculated with different load conditions. The output waveform is measured.
