摘要：
This paper proposes a novel voltage-control scheme to improve the slow dynamic response of the conventional pulse-width-modulation (PWM) continuous-current-mode (CCM) voltage-programming DC-DC converter. By introducing a high-pass notch Alter in the control loop of the conventional converter, the unity gain bandwidth of the loop gain is enhanced and the system Q value is decreased. To demonstrate the improvement in the transient response, voltage-programming PWM CCM DC-DC converters with both the conventional and the proposed control schemes are designed and simulated. Results show that the dynamic response has 10 times improvement.
