Abstract: A new control technique, multilevel pulse train (MPT), for switching converters is proposed in this paper. By using MPT control, according to different operation states, multilevel pulses are combined to generate a multilevel pulse train for the control of switching converters. MPT control technique is easy to realize, with great robust ness and good transient performance. The principle and implementation of the control technique are introduced, and the operation, characteristics and small-signal model of MPT controlled buck converter are also studied. The analysis, simulation and experimental results show that MPT control technique has much faster transient response than traditional PWM control technique and much lower output voltage ripple than the pulse train control technique.
