Abstract
The present disclosure relates to a bidirectional semiconductor circuit breaker including a primary circuit unit connected between a power supply and a load and in which a first semiconductor switch and a second semiconductor switch are arranged in series and a snubber circuit unit of which one end is connected to the front end of the first semiconductor switch and the other end is connected to the rear end of the second semiconductor switch, in parallel. The snubber circuit unit includes a first circuit line, a second circuit line, and a third circuit line of which one end and the other end are connected to the first circuit line and the second circuit line, respectively, and in which a first resistor and a second resistor are arranged in series, and provide a snubber circuit which is applicable to a bidirectional fault current and satisfies semiconductor protection and current restraining performance.
