| 摘 要： | 逆变电源输出功率的调节方式有多种,分析了逆变电源的功率控制原理,阐述一种采用软开关相移脉宽调制(Phased Shifted Pulse Width Modulation,简称PSPWM)方式的功率调节,对其工作原理进行分析和仿真,同时设计了基于DSP的串联谐振式逆变电源系统并进行实验.仿真和实验结果均表明,采用基于DSP的PSPWM功率控制方式能实现逆变电源的输出功率调节,开关器件工作在零电压开通和关断状态,大大减小了器件的功率损耗,提高了系统的整体效率.

| Abstract: | There are lots of methods about the output power regulation in inverter.The principal of power regulation in in-verter is analysed.A power regulation method of soft switching phased shifted pulse width modulation (PSPWM) is intro-duced,and the system of series resonant inverter based on DSP is designed.The simulation and experimental result proved that the PSPWM power control method based on DSP can regulate the output power,and the switch devices work under the condition of zero voltage switching,thus the ... |
