Abstract: A DC to AC inverter includes a bridge type switch circuit, a transformer, an integrated circuit, a pulse width modulator, a wave generator and a control-drive circuit. The switch circuit is connected to a direct current power source and has two alternating current ends with one of the alternating current ends connecting with an energy storage inductor in series and then connecting with an input end of the transformer and the other input end of the transformer being connected to the other alternating current end. The current waves at both of the alternating current ends are detected and the waves are integrated and sent to a feedback end of the pulse width modulator. The wave generator produces half period of sine waves for a reference potential end and low frequency (50 Hz or 60 Hz) square waves for the control-drive circuit operating the pulse width modulator and the square waves and sending control signals to the switch circuit.
