| 摘 要： | 提出了一种新型的基于单周期控制的单位功率因数整流器为井下电机车供电。该电源由维也纳整流级和高频隔离DC-DC变换级两级功率变换器级联构成,但控制电路采用一级协调控制。电路控制简单,不需要乘法器和输入电压检测就可以实现单位功率因数运行,且可以降低开关器件一半的电压应力。详细分析了新型整流电路的基本工作原理和双闭环控制策略,并通过仿真和试验对此新型电路拓扑及其相应控制策略的正确性进行了验证。

| Abstract: | A new type of unit power factor rectification based on single cycle control One-Cycle Control (OCC) was proposed. The circuit was powered by a downhole electric locomotive. The power supply was composed of a rectifier stage based on cascaded vienna rectifier and a transmission stage based on high-frequency isolated DC-DC converter. However, an overall control scheme was adopted to regulate the two stages. This simple control scheme could realize the unity power factor without involving any multipliers or input voltage sensors. Besides, the voltage pressure of the switches could be reduced by half due to the topology structure. The basic operating principles and the double-loop control strategy were analyzed in detail. The correctness of the proposed circuit and its corresponding control strategy was verified by simulation and experiment. |
