基于开关稳压电源与开关稳流电源并联系统的设计

摘要

To improve the performance of the power, increase the ability of the power to adapt to changes in load, this paper will be designed a power supply system that is built with switch the voltage source and the switch current source in parallel.System uses the output current proportional allocation method at the voltage source and current source in parallel, the problem of output instability is solved af-ter the parallel switching power supply system, the actual parallel power system is constructed.Experi-ments show that this current is automatically allocated pro rata method, can achieve the stability of the power system output power.%为了改善电源的性能，提高电源对变化负载的适应能力，设计将开关电压源和开关电流源并联构建供电系统。系统采用电压源与电流源在输出端并联后按比例分配输出电流的方法，解决开关电源并联后供电系统输出不稳定的问题，构建了实际的并联电源系统。实验表明，采用该文的按比例自动分配电流的方法，可以实现电源系统的大功率稳定输出。
