摘　　要：针对电压型高频链逆变器的控制,论述了一种新型数字正弦脉宽脉位调制(SPWPM)控制策略,分析了该控制策略的工作原理,并利用C8051单片机实现了该控制系统的算法。样机实验结果表明,采用该控制策略的逆变器克服了传统SPWM模式逆变器的缺点,既具有高频电气隔离功能,又有电路拓扑简洁等优点。实验结果也证实了该逆变器及其控制系统的可行性和有效性。A novel digital sine pulse width and position modulation （SPWPM） control strategy is discussed in this paper according to the control of voltage mode high frequency link inverter.The principle of the method is analyzed,and the realization of the control arithmetic is based on MCU C8051.The experimental result of a prototype shows the inverter adopted this control strategy overcomes disadvantages of traditional SPWM model inverter,proves many advantages such as high frequency electric isolation,concise circuit topology,and has also confirmed the feasibility and availability of the inverter and the control system.
