Abstract :
A new peak current control scheme with capacitor voltage balance compensation for duty-cycle-shifted (DCS) half-bridge is proposed. The voltage balance is achieved by the control circuitry without modifications on the power stage. The implementation control circuitry is simple and easy to be integrated. The scheme is verified by experiment prototype
