  • In order to solve the problem that DC-DC converter switch has a large steady-state output voltage ripple in pulse train (PT) control, a variable width pulse train (VWPT) control method was proposed after analysis of the generating mechanism of large output voltage ripples. The VWPT control method is based on a buck converter operated in discontinuous conduction mode (DCM). According to the load power change, the duty ratios of high and low power pulses can be regulated dynamically by digital control, and then the converter can be controlled by two drive pulses with small energy discrepancy. Thus, the characteristics of output voltage ripple in VWPT control are obviously better than in PT control. The experimental results show that the steady-state output voltage ripple in VWPT control can be reduced about 50% compared with that in PT control.
