Study on the DC-DC Converter with Impulse Sequence Control

According to the problems in the DC/DC converter control technology, a novel DC/DC converter topological structure was proposed in this paper, and achieved its control in discontinuous conduction mode (DCM) by using pulse-sequence (PS) control method To avoid cross-regulation between each output of multiple output fly-back converters, time-multiplexing scheme is used to determine which output is controlled in the time interval of time-multiplexing signal. Error amplifier and corresponding compensators as required by conventional pulse width modulation technique are not needed in PS control; the multiple output fly-back converters with PS control proposed in this paper is simple and enjoys fast dynamic response. The simulation and experimental results further verify the analysis results.
