| Abstract |
This paper describes the simple single phase air-conditioner of power factor correction (PFC) circuit. By adopting PFC in the rectifier, we can reduce harmonic into power line, improve the efficiency and lower the total system cost compared to conventional inverter only. Also, system performance is improved by stabilizing the output voltage of PFC. To improve the current waveform of diode rectifiers, we propose a new operating principle for the voltage diode rectifiers. A circuit design method is shown by experimentation and confirmed simulation. It explained that compared conventional pulse-width modulated (PWM) inverter with half pulse-width modulated (HPWM) inverter. Proposed HPWM inverter eliminated dead-time by lowering switching loss and holding over-shooting. |
