On the use of pre-calculated switching angles to design a new single-phase static PFC inverter

A new method for static power factor correction (SPFC) is presented in this paper. To perform the PFC operation, a static system is used to compensate four-quadrant reactive power using only small capacitance values. SPFC is also able to deal with different load characteristics that can be inductive and/or capacitive. The proposed method combines a passive filter and an inverter with pre-calculated PWM switching angles. The obtained system produces low harmonic distortion thus providing reliable and long lasting system components. Simulation results shows that the system is able to provide variable positive and negative true and reactive power while keeping the passive system components values constant
