【摘要】 本文针对风机负载的特点,提出了一种硬件少,易于软件化的PWM(Pulse-Width Modulation)生成方法——电压矢量PWM法.采用单片机实现了全数字控制,并在GTR逆变器上进行了试验.结果表明:电压矢量PWM控制算法应用在风机负载上具有优越性.更多还原

【Abstract】 According to the charaeteristics of fan-type load, this paper presents a PWM generation method-voltagel vector PWM control which needs a little computation and hardware. A full digital PWM control using MCS-51 single-chip microprocessor is realized and tested on GTR inverter. The results proves the advantages of this control algrorithm.更多还原
