| Abstract: | It analyzed the circuit diagram of four-phase interleaved buck converter. A control scheme which combines PID controller and one-cycle control（OCC） was proposed to enhance dynamic response of converter output voltage. The converter with the proposed method has few output ripples and good robustness. The theory and simulation experimental results demonstrate its feasibility and validity. |
