Abstract :
A versatile DC-DC and DC-AC capacitively coupled power converter which is capable of zero current soft switching is presented. This converter can supply both DC and AC loads with a higher system efficiency due to its zero current switching operation. The DC output is regulated by pulse width modulation (PWM) while the AC waveform is controlled by amplitude modulation (AM) and discrete pulse modulation (DPM). This versatile converter is suitable for high power high efficiency applications, such as solar energy conversion and uninterruptible power systems (UPS)
