Power Factor Correction Using Single Stage Discontinuous Conduction Mode Booster Rectifier

A single stage three-phase power factor correction circuit using a boost input current shaper has been described in both simulation and experimental work. To reduce the cost and avoid complexity the boost dc-to-dc converter is operated in discontinuous conduction mode using only one active switch...

The variations of the small signal model against load are demonstrated, and the compensator designed for constant switching frequency PWM is discussed.
