THE COMPARISON OF AVERAGE AND HYSTERESIS CURRENT MODE CONTROL TECHNIQUE OF SINGLE PHASE BOOST POWER FACTOR CORRECTION CONVERTER

In this study, single-phase ac-dc boost converter with power factor correction (PFC) is presented. This converter reshapes the distorted input current waveform to approximate a sinusoidal current that is in phase with the input voltage. There are several effective techniques for achieving a sinusoidal input current waveform with low distortion. Two typical techniques for PFCs are average current mode control (ACMC) and hysteresis current mode control (HCMC). These control techniques are evaluated according to the control strategy, circuit components, and total harmonic distortion of input current. The boost converter is operated in continuous conduction mode (CCM). Both control techniques are simulated in Matlab/Simulink program.
