  pfc circuit
Since a PFC circuit keeps the mains current and voltage in phase with very low distortion, mains power integrity is maintained.
      
The current and voltage values have been extracted from the simulation results of the PFC circuit in PSIM.
      
The output of the PFC circuit is fed into an inverter to obtain high frequency pulses to the output.
      
While a third device serves duty in the main PFC circuit as the power switch that drives the PFC inductor.
