    摘要: A permanent magnet (PM) electric generator with directly controllable field excitation control comprises: a drive shaft; a PM rotor assembly with multiple PMs arranged around an outer axial periphery of the rotor assembly; a stator assembly comprising a ferromagnetic stator yoke, multiple ferromagnetic stator teeth mounted to the stator yoke with distal ends proximate the outer axial periphery of the rotor assembly separated by an air gap and multiple stator coils mounted between the stator teeth; multiple saturable ferromagnetic shunts, each shunt coupling adjacent distal ends of the stator teeth to shunt air gap magnetic flux Φg generated by the PMs across the air gap through the distal ends of the stator teeth; and multiple saturation control coils, each saturation control coil wrapped about a saturable region of an associated one of the shunts; wherein application of a control current Ic to the control coils at least partially magnetically saturates the shunts to reduce shunting of air gap magnetic flux Φg, thereby increasing magnetic flux linkage ΨM between the PMs and the stator coils and increasing generated electromagnetic force (EMF) at lower levels of rotor assembly angular velocity.

    摘要: A power management and distribution (PMAD) system includes a main DC bus, an auxiliary DC bus, a power converter, one or more hybrid solid-state circuit breakers, and a controller. The power converter converts power from the main DC bus to provide a regulated output to the auxiliary bus. Each hybrid SSCB includes a main switch connected between the main DC bus and a load and an auxiliary switch connected between the auxiliary DC bus and the load. The controller selectively turns the main switch and the auxiliary switch On/Off to selectively supply power from the main DC bus and/or the auxiliary DC bus to the load, and to selectively regulate the voltage on the auxiliary DC bus.

    摘要: A system for controlling a solid state circuit breaker comprises a solid state power switch, and a controller for providing a gate voltage to the power switch. During turnoff of the solid state power switch, the controller reduces the gate voltage to an intermediate level for a specified time period and then reduces the gate voltage to a turnoff level.
