| 摘 要： | 针对能量回馈型同相供电系统中单相H-H功率单元的PWM整流器,提出了一种电压、电流前馈的双闭环控制策略。同时,针对大功率、低开关频率应用场合,给出了一种调制方法,解决系统延时带来的控制性能下降问题。最后,基于数字信号处理器(DSP)与复杂可编程逻辑器件(CPLD),构建了兆瓦级单相PWM整流器硬件装置。实验结果表明,系统运行稳定,动、静态性能符合指标要求。

| Abstract: | Aiming at the PWM rectifier of the single-phase H-H power unit in the regenerative cophase power supply system,a double closed-loop control strategy is proposed with the feed forward of voltage and current.Meanwhile,for high power and low switch frequency system,a modulation method is put forward to solve the deterioration of the control performance caused by the big modulation delay.Finally,based on digital signal processor(DSP) and complex programmable logic device(CPLD),a hardware system of power unit is built.The experimental result indicates that the system is reliable and stable,and the static and dynamic performance meet the requirements. |
