| Research Abstract |
The present research deals with a low-voltage DC (Direct Current) solid-state circuit breaker utilizing the switching function of a power semi-conductor device. An IGBT (Insulated Gate Bipolar Transistor) was employed. In consideration of a dependence of a corrector-emitter resistance on a gate-emitter voltage, circuit configuration of circuit-breaker components was contrived to achieve limiting and breaking operations of the direct current. The model IGBT-type DC circuit breaker was constructed to perform the current-breaking experiment. The experimental results demonstrated that the model circuit-breaker successfully interrupts the current of the 10-80 A under the source voltage of DC 120 V. The results also verified that adjustment of the time constant τ_<GE> in the gate circuit allows control of the interrupting time t_<int>. A thyristor was also discussed to construct the low-voltage DC circuit breaker.
