Abstract
An inverter includes a pulse width modulation (PWM) circuit, a direct current (DC) voltage input terminal, a storage capacitor, a first transformer, a soft start circuit, and a first transistor. The PWM circuit includes a first output terminal. The first transformer includes a first primary winding. The first primary winding includes a first terminal and a second terminal capable of being grounded via the storage capacitor. The soft start circuit includes an inductor and a first capacitor. A gate electrode of the first transistor is connected to the first output terminal. A source electrode of the first transistor is connected to the first terminal of the first transformer via the inductor. A drain electrode of the first transistor is connected to the DC voltage input terminal and connected to the source electrode via the capacitor.
