An inverter circuit is provided to protect the circuit by stopping operation of the circuit in case that an abnormal signal such as peak voltage due to noise is included in a PWM(Pulse Width Modulation) signal as an inverter driving signal. An inverter circuit includes a switching unit(11), a driving unit(12), and a circuit protection unit(13). The switching unit switches inputted power to transmit the power to a secondary side of a transformer(T). The driving unit receives a PWM(Pulse Width Modulation) signal from an inverter driving IC(Integrated Circuit) to control the switching unit. The circuit protection unit determines whether an abnormal signal is included in the PWM signal and blocks a signal for driving the driving unit when the abnormal signal is detected. |
