This paper explores pulse train controlled boost converter operating in discontinuous conduction mode (DCM). By analyzing the output voltage variations under the high and low power pulse controls in each switching cycle, the paper also investigates the high and low power control pulse combinations and output voltage ripples in a power pulse train repetition cycle of pulse train controlled DCM boost converter with different loads are investigated, which provide the necessary basis for the design of pulse train control scheme. By using PSIM circuit simulations, the time-domain waveforms under different loads are obtained. Simulation results verify the correctness of the control pulse combinations and ripple analysis results and the feasibility of the proposed control scheme. The analysis methods and research results in this paper possess important guiding significance in the design and operation of pulse train controlled switching converters.
