Abstract A new control technique for switching DC/DC converter, Multilevel-Pulse Adjustment (MPA), is proposed in this paper. Based on the output voltage error at the beginning of each switching cycle, MPA controller selects one control pulse among multilevel pulses as the control signal of converter at this switching cycle. The principle of the proposed control technique is analyzed and discussed. The operation states and small-signal model of MPA controlled Buck converter operating in discontinuous conduction mode are analyzed and studied. Analysis results show that MPA scheme is easy to realize, has great control robust, transient and steady state performance. The simulation as well as experimental results verifies the advantage of the proposed control techniques.
