Real implementation of synchronous boost converter with controller for power factor correction

Power factor and harmonics are primary factors in electrical distribution network. Harmonics are generated by the non-linear and irregular loads at end users. High harmonics in devices draws the large amount of current which results in poor power factor. Hysteresis control technique is one of the techniques in power factor converter topologies. Switching losses, low power factor and high harmonic distortion factors have been observed in present topology. To overcome these problems, synchronous PFC boost converter with controller has been proposed. This control scheme improves power factor (PF) and minimizes current harmonics. Advantages of proposed control technique includes low switching losses, low harmonic distortion, nearly unity power factor and bidirectional power flow. This conceptually built low cost synchronous PFC boost converter with controller has been tested and demonstrated for its functionality.
