Analysis of Power Factor Corrector Energy Efficiency in the Off-Line Power Supply Systemswith Wide Range of Input Voltage
The article describes the operating principle of a single-phase bipolar power factor corrector (PFC) with low level of the input sinusoidal voltage. Analytical equations were derived for power losses computing in the semiconductor components for both single-phase classical (boost) and a bipolar PFC, and comparative analysis of power losses computing for both structures was performed. Simulation Spice models of both classical (boost) and a bipolar PFC were developed. Verification of power losses values obtained by analytical calculation with the simulation results was performed.
