摘要：
Pulse width modulation (PWM) has been one of the most conventional modulation techniques for switching dc-dc converters. It compares error signal with sawtooth wave to generate the control pulse. Conventional PWM control technique suffers from slow dynamic response due to smooth error signal variation under step line or load variation. A novel PWM control (modulation) method for switching dc-dc converters with improved dynamic response is proposed in this paper. Simulation results show that the proposed control method has much faster dynamic response than that of conventional PWM control technique.
