ABSTRACT
Power factor correction (PFC) is the capacity for generating or absorbing the reactive power produced by a load [1-3]. Power quality issues and regulations require rectifier loads to be connected to the utility to achieve high PFs. This means that a PFC rectifier needs to draw close to a sinusoidal current in phase with the supply voltage, unlike phase-controlled rectifiers (making the PFC rectifier “look like” a resistive load to the utility).
