Abstract
A DC-AC converter is provided. The DC-AC converter includes a time-varying DC power generating circuit, an AC power generating circuit and a transmission capacitor. The time-varying DC power generating circuit is controlled by a pulse width modulation (PWM) signal to transform a DC source into a time-varying DC power. With reference to the time-varying DC power, the AC power generating circuit is controlled by a first polarity switching and a second polarity switching signal to generate an AC power. The transmission capacitor, coupled to the time-varying DC power generating circuit and the AC power generating circuit, transmits the time-varying DC power from the time-varying DC generating circuit to the AC power generating circuit.
