Breaker and a half configuration
WebCompared to a bidirectional IGBT solid-state circuit breaker module, B-TRAN reduced the voltage drop more than fourfold. An IGBT-based bidirectional switch recorded a voltage drop of 2.75 volts when the load current was positive, versus a drop of 0.6 volts for the B-TRAN breaker. The B-TRAN switch also reduced the amount of power loss. WebContexts in source publication.
