Abstract:
A circuit comprising a primary section and a multiple voltage secondary section. The multiple voltage secondary section includes a multiple voltage resonance section, a filter section, and a load coupling section. The circuit also includes a transformer, which is operatively configured to couple the primary and secondary sections. The multiple voltage resonance section includes a capacitance, i. e. , an Alexander Topology. This capacitance, which is preferable based on series capacitors, operatively generates a predetermined voltage, such that a turns ratio of the transformer is lower than a non-multiple voltage resonance section to generate the predetermined voltage. Hence, this configuration decreases energy loss from the transformer, thereby increasing efficiency.

Abstract:
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.

Abstract:
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.

Abstract:
A system for controlling the excitation of an alternator field coil. The system comprises a capacitor forming a charge reservoir, a first and a second selectively operable switch connected to opposing ends of a field coil of the alternator, a first catch diode, and a second catch diode. At least one of the first and second switches are operated at a variable duty cycle and the capacitor both absorbs energy from the field coil and supplies energy to the field coil to regulate the magnetic field of the field coil, effective to regulate the output voltage of the alternator and rapidly compensate for changes in at least one load connected to the alternator.

Abstract:
A high-frequency transformer. The transformer comprises a high-voltage winding. A first bus bar is positioned proximate the high voltage winding and extends to a first portion of a plurality of power switching devices. The first bus bar is electrically coupled to the first portion of the power switching devices. A second bus bar is positioned proximate the high voltage winding and extends to a second portion of the power switching devices. The second bus bar is electrically coupled to both the high voltage winding and the second portion of the power switching devices. A third bus bar extends between the first and second bus bars and is electrically coupled to the first bus bar, second bus bar, and the high voltage winding. The second and third bus bars form a low voltage winding that electrically cooperates with the high voltage winding to form the high-frequency transformer.
An electrical system control for a vehicle having a charging source, a first battery connected in series with a second battery to form a primary power supply that is connected to the charging source, and a third battery forming a secondary power supply. The system comprises a first bidirectional battery equalizer connected to the charging source and further connected to the second battery, a second bidirectional battery equalizer connected to the charging source and further connected to the third battery, and a controller adapted to monitor the state of at least one of the charging source and the first, second and third batteries. The controller also controls the operation of at least one of the first and second bidirectional battery equalizers in a predetermined manner, effective to control the charge and discharge of at least one of the first, second and third batteries.
