An object is to reduce, with the control circuit of the full-bridge inverter circuit, distortions in an output signal of the inverter circuit resulting from an error in control of the switching of the high-side transistors and low-side transistors included in the first half-bridge circuit and the second half-bridge circuit. The pulse width of a signal that controls ON/OFF of the high-side transistors and low-side transistors included in the first half-bridge circuit and the second half-bridge circuit is reduced, i.e., the duty cycle of the signal is reduced. This results in a reduction in short-circuit periods during which both the high-side transistor and the low-side transistor are on, thereby reducing distortions in a signal.
