【摘要】针对现有直流斩波器测试平台存在电源输出纹波大、大功率负载选择难、测试效率低和测试能耗大等问题,提出了一种基于能量自循环模式的矿用直流斩波器测试平台。该平台采用三相变压器+三相不控整流电路+Buck电路和恒压限流控制策略实现可调电压源输出电压0~750 V,采用Boost电路和恒流控制策略实现能量自循环负载输出电流0~240 A,从而实现电压和电流大范围调节,提高测试效率;同时将能量自循环负载输出能量反馈至可调电压源输出端,实现能量自循环,降低测试能耗。仿真和试验结果验证了该平台的有效性。
【Abstract】For problems of large ripple of power supply, difficult selection of high-power load, low test efficiency and high test energy consumption existed in existing DC chopper test platform, a mine-used DC chopper test platform based on energy self-circulation mode was proposed. The platform uses three-phase transformer, three-phase uncontrolled rectifier circuit, Buck circuit and constant voltage and current limiting control strategy to achieve adjustable voltage source output voltage of 0-750 V, and adopts Boost circuit and constant current strategy to realize energy self-circulation load output current of 0-240 A, so as to realize large-scale adjustment of voltage and current and improve test efficiency. Meanwhile, output energy from the energy self-circulation load is fed back to output end of the adjustable voltage source to realize energy self-circulation and reduce test energy consumption. The simulation and experimental results verify effectiveness of the platform.
