Summary: | The utility model provides a DC/AC conversion circuit. The DC/AC conversion circuit comprises a push-pull type pulse width modulation circuit, a rectifying circuit, a second filter circuit, an inverter circuit, an amplifying circuit and a third filter circuit. The push-pull type pulse width modulation circuit is connected with the positive electrode input end of a DC voltage source, comprises a PWM controller and two MOSFETs, and is used for converting input single-path DC voltage into double-path PWM impulse voltage. The rectifying circuit is connected to the output end of the push-pull type pulse width modulation circuit and used for rectifying the PWM impulse voltage to form forward-direction semiwaves and negative-direction semiwaves, so that two output ends are formed. The second filter circuit is connected with the two output ends of the rectifying circuit so that the forward-direction semiwaves and the negative-direction semiwaves can be converted into stable forward-direction and negative-direction do |
