Boost PFC
Description
It is the simplest and most commonly used PFC circuit, consisting of a single boost converter. The desired current waveform can be generated by switching operation, and the power factor can be made close to one.
Overview
- Typically SJ MOSFET and SiC diodes (or FRD)
- Efficiency around 98%
- Frequency 70 kHz to 130 kHz
- Full load and nominal efficiency only guaranteed for 230 V AC
