| Abstract |
This paper deals with a transient characteristics improvement of a resonant switched capacitor converter(RSCC)based on phase shift control method, which has capability of accurate voltage regulation by means of applying a voltage feedback control. The analysis in this paper reveals that the RSCC may superpose an unwanted current on the resonant current and cause voltage fluctuation and/or over current in a transient state. This paper proposes a modified phase shift control method including the sequence and timing control of the gate signals, resulting in elimination of the unwanted current from the resonant current. Experimental results verify the validity of the proposed control method. |
