The hybrid compensation system provides to reach unity power factor through the coordinated control of a synchronous motor and switched capacitors. In the proposed structure, switched capacitors produce the main part of reactive power demand, while the power requirement between the stages is met by a synchronous motor. With the help of
Switched capacitors can absorb charge from the load or release charge to the load to suppress voltage fluctuations and improve the transient response. A 12 V–0.9 V buck converter with a switched capacitor charge compensation auxiliary circuit is built and verified. Section 2 introduces the principle of switched capacitor charge compensation.

Fig. 5(a) shows a Miller compensation capacitor, used to split the poles associated with nodes X and Y. In addition to pole splitting, the Miller capacitor Gm forms a feedforward path resulting in an RHP zero, located at [5], [6] 9mY Wz = + Gm . (3) C. Shifting the Miller zero from RHP to LHP The Miller RHP zero can either be cancelled or shifted to the LHP by choosing an appropriate
Compensation capacitors are used to counteract reactive current (increased power factor) and are basically either connected in parallel or in series. Compensation capa-citors are not required when using electronic ballasts, whose power factor is generally in the region of 0.95.
