Experimental Researches on Resonant Reactor-Based Single-Phase Passive PFC

Anovel resonant reactor based single-phase passive PFC is introduced to correct the input power factor of the inverter appliances powered by single-phase mares. The entire circuit is simulated and experimented alter analysis, and related many waveforms and data tested are gained. The optimal design approach to parameter design is also depicted. It proves that the passive PFC features good correction effect, high out voltage yield, convenient heat sink and installation, low cost. and so on, and it can works as a higher power passive AC-DC converter to feed the post inverter.
