Abstract :
Three-level boost PFC converter has advantages of lower inductor current ripple and lower switch withstanding voltage than the boost PFC converter. Interleaved current sensorless control (ICSC) had been proposed for multiphase boost PFC converters. In this paper, ICSC is modified for current sensorless control of the three-level boost PFC converter with the asymmetric loads. The modified interleaved current sensorless control (MICSC) is implemented in a field programmable gate array (FPGA) board. Simulation results and experimental results are also provided to validate the proposed MICSC.
