Abstract
This paper describes a new dc/ac inverter system, which makes use of parallel loaded high frequency resonant inverter consisting of full bridge, for achieving sinusoidal ac waveform. Because current throughout switch at turn-on is always zero in proposed inverter, low stress and low switching loss is achieved. Operating characteristic of proposed system is analyzed in per unit system using computer simulation. Output voltage of it include low harmonics and almost close tn sine wave.
