【Abstract】 This article introduces the hardware and software design project of using microcomputer of MCS-51 series to generate pure sinusoid AC. This means is more accurate than the means of using hardware and software to generate SPWM. It has proved that using the means above can not only simplify the device, enhance the reliability of the system, but also the characteristic of every aspect is superior to traditional system.更多还原
