350W Power Factor Boost Converter for Inverter-Fed BLDC and PMSM Motors
This 350W power factor boost converter is designed for inverter-fed BLDC/PMSM motor appliances, A/C units, Refrigerators, and industrial power supplies. The circuit is a continuous-conduction-mode boost converter implemented using a UCC28180 PFC controller module which provides all the necessary built-in protections. It’s a robust output supply protected for output cover current, output over-voltage, and output under voltage conditions. The converter has two parts, the main power board and the UCC28180 PFC controller/Breakout board. PFC boost converter provides 380VDC regulated output at 0.9A load current. The PFC converter accommodates an input voltage range of 85VAC to 265 VAC and uses average current mode control at a fixed programmable switching frequency of 120Khz.
Features
- Output 380V DC
