Patent number: 5936422Abstract: A hybrid vehicle utilizes a power unit to store and convert power between a turbine alternator, flywheel, and traction motor. The power unit uses a plurality of power transistors for switching power to the equipment. The transistors are set in an H-bridge configuration to provide AC power. The H bridge configuration comprises two transistor pairs, each forming a half bridge. A process for matching the transistor pairs of each half bridge includes measuring the electrical and timing characteristics associated with turn on and turn off with a first transistor module, and measuring the electrical and timing characteristics associated with turn on and turn off of each of a plurality of transistor modules. The electrical and timing characteristics associated with each of the plurality of transistors modules is compared against the electrical and timing characteristics of the first transistor module.Type: GrantFiled: May 2, 1996Date of Patent: August 10, 1999Assignee: Chrysler CorporationInventors: Kevin J.

Patent number: 5929612Abstract: In an induction generator, an additional set of stator windings is provided, separate from and secondary to the main stator windings upon which the generator's output voltage is generated and supplied to the load. This separate stator winding is provided for the purpose of supplying the generator with the reactive electrical power it needs to maintain the rotating stator field and supplying any reactive power needed by the load. Thus, there is no need to use a capacitor assembly, for supplying the reactive power needed by the generator. Currents are injected into this separate winding in such a way that only reactive power is supplied to the generator. Specifically, a power measuring circuit measures the power in the additional set of stator windings, and a power error signal is formed by algebraically adding the outputs of the power measuring circuit.Type: GrantFiled: July 3, 1997Date of Patent: July 27, 1999Assignee: Satcon Technology CorporationInventors: David B.
