Abstract

In order to increase the applicable input voltage scope of Pulse Adjustment (PA) controlled converter, a new control technique for DC-DC converters, Multiple Sets of Pulse Adjustment Based on Input Voltage Feed-forward Compensation (IVF-MSPA), is proposed in this paper. By introducing input voltage feed-forward compensation, at the beginning of each switching period IVF-MSPA controller senses the input voltage of the DC-DC converter and selects one among multiple sets of control pulses. Each set of control pulses is composed of high-power pulse and low-power pulse. The high-power pulse or low-power pulse is selected to drive the power switch by sensing the output voltage of the DC-DC converter at the beginning of each switching period. The principle and operational process of IVF-MSPA control technique are introduced in the paper. The control regulation and steady-state performance of IVF-MSPA controlled Boost converter operating in discontinuous conduction mode ( DCM ) are studied. The proportions of IVF-MSPA and PA control pulses as the function of input voltage within one repetition cycle are analyzed. Simulation and experimental results are presented to verify the feasibility and advantages of IVF-MSPA control technique as well as the correctness of the theoretical analysis. Research results show that the IVF-MSPA controlled converter enjoys excellent steady and transient state performance as well as the wider input voltage scope.
