Original Abstract Submitted

A half-bridge circuit includes a series of a first high-voltage MOS, a first low-voltage MOS, a second high-voltage MOS, and a second low-voltage MOS. The half-bridge circuit further includes a capacitor, and the capacitor is connected to the first high-voltage MOS and the second low-voltage MOS. The voltage of the capacitor is greater than 300 V. The drain-to-source withstanding voltage of the first high-voltage MOS is higher than the drain-to-source withstanding voltage of the first low-voltage MOS by 10 times or greater. The voltage of the capacitor is higher than the drain-to-source withstanding voltage of the first low-voltage MOS by 10 times or greater.
