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. WebMotor rotor magnetic bridges operate under multiple physical field loads, such as electromagnetic force, temperature, and centrifugal force. These loads can cause fatigue and aging failure of the bridges, especially when the rotor is operating continuously at high speeds and high temperatures.
