摘　　要：在进行综合性实验时,存在需要多性质多电压等级电源供电、线路杂乱易产生安全隐患等问题.对此提出一种交直流输出调压电源.电源前级全桥整流与全桥DC-DC变换器实现电压的升高与隔离转换,后级变换器共用直流母线实现输出通道扩展,每路独立控制调压输出.在Matlab/Simulink仿真平台中构建了电源模型,研究了电源的交直流输出特性与负载能力.结果表明电源拓扑与控制策略的正确性,电源可快速精准地实现调压变频输出.When conducting comprehensive experiments,there are problems such as the need for power supply with multi-nature and multi-voltage levels,and the potential safety hazards caused by the disordered lines.In this paper,an AC-DC voltage regulation power supply is proposed.The front stage full bridge rectifier and full bridge DC-DC converter of the power supply realize the voltage rise and isolation conversion,and the rear stage converter shares the DC bus to expand the output channel,with each circuit independently controlling the voltage regulation output.The power supply model is built in Matlab/Simulink simulation platform,and the AC-DC output characteristics and load capacity of the power supply are studied.The results show that the power topology and control strategy are correct,and the power supply can realize voltage regulation and frequency conversion output quickly and accurately.
