Abstract:
Power factor, current harmonics and crest factor are very important for power transmission and distribution systems. In this moment, the most of loads are power electronic circuit that is rectifier circuit. This rectifier circuit consists of diodes and large capacitance, therefore made power factor is low, current harmonics and total harmonics distortion (THD) are high. This thesis concentrated on power factor correction, low current harmonics and total harmonics distortion (THD). By used the boost converter and high switching frequency. The output of the boost converter is supplied to bridge inverter for capacitive load. This bridge inverter is a new pulse width modulation technique that drive power switch. This capacitive load is Electroluminescent (EL) and output voltage is nearly sine wave. High input power factor and low current total harmonics distortion (THD) can be obtained.
