In this paper, a control circuit is designed, which can reverse the direct current into alternating current. This circuit is based on STC12C5A60S2 MCU, using its PCA function to achieve two SPWM signals, then inverts DC 12V to AC 24V. The data test shows that the AC voltage obtained by this device is stable and the frequency error is small, so it can be applied to the demand field of small-scale inverters.
