Abstract :
A technique for efficiently producing low-harmonic, 60 Hz sinusoidal 110 V AC from a 24 V DC source without inductors or transformers is presented. The novel circuit topology allows the same power MOSFETs that sequentially charge a bank of capacitors to synthesize the staircase sine wave approximation. A Fourier analysis of the effects of MOSFET on-resistance and switching time on a 1 kW prototype is presented
