초록
A Single-phase Active Rectifier (SAR) [4-6] with high power factor capability is adopted to satisfy the international harmonic current standards such as IEC 1000-3-2. To minimize the input current distortion and to apply the control IC, such as FA5331, UC3854, ML4821 and so forth, the new adequate sensing circuits of the input voltage and current are proposed. There are tow methods applicable the SAR to inverter air-conditioner from the viewpoint of both efficiency and cost. The selecting methods of the passive components are presented for the two approaches. Using the determined components, the loss analyses are carried out. The prototype SAR circuits of these two approaches with 3kW power consumption are built and the operation and performance of the circuits with power factor correction capability are verified through the experimental results.
