    摘要: A high-frequency DC-DC converter. The high-frequency DC-DC converter comprises a resonant power stage and a controller to operate the resonant power stage. The resonant power stage is controlled by the controller with at least one of a variable frequency mode and a pulse width modulation mode to convert an input DC voltage to one of a higher output DC voltage and a lower output DC voltage.

    摘要: A method and apparatus are taught for driving a gate of a power device to turn on the power device utilizing a lossless gate driver circuit. The circuit comprises in parallel a power section, a rectifying section, a switching section, a capacitance, and an anti-spiking section. The circuit further comprises a transformer section coupled to the rectifying section, the switching section, and the anti-spiking section and a power device coupled to a portion of the anti-spiking section. The system is configured to regenerate substantially all energy utilized to power the power device via the coupling of the transformer section to the rectifying section, the switching section, the capacitance, and the anti-spike section.

    摘要: A power management system for a vehicle. The system may be flexibly configured using various arrangements of DC to AC inverters, DC to DC converters AC to DC converters, DC to AC converters and AC to AC converters, one or more batteries, and a control portion to provide an AC bus, a primary DC bus and a secondary DC bus. The control portion monitors the status of the buses, inverters and converters and controls the operation of the inverters and converters to supply and regulate the power supplied by the buses. The inverters and converters may be bidirectional, allowing power to be transferred between buses.
