Abstract
To improve the current waveform of diode rectifiers, we propose a new operating principle for the voltage diode rectifiers. In the conventional voltage rectifier circuit, relatively large capacitors are used to boost the output voltage, while the proposed circuit uses smaller ones and a small reactor not to boost the output voltage but improve the input current waveform. A circuit design method is shown and confirmed simulation. It explained that compared conventional SPWM inverter with HPWM(Half Pulse-width modulated)Inverter. Proposed HPWM inverter eliminated dead-time by lowering switching loss and holding over-shooting. Output voltage and current of this paper were applied for real air-conditioner.
