【Abstract】 This article introduced a design method of intelligent power, which use the system on C8051F410 chip as the core, generating controlled PWM wave, which can generate sinusoidal signal output of small distortion and high efficiency through control circuit and filter unit. Adjust space occupation ratio by comparing given value and DA output to obtain steady voltage output. Stable amplitude control and over-current protection can be achieved through the detection of output voltage and current.更多还原
