DUAL COIL GENERATOR

摘要

A vehicle electrical system comprises a generator which provides electrical power to an electrical load. The generator includes two field coils. A first switch circuit is coupled with the first field coil and a second switch circuit is coupled with the second field coil. A control device, included in the electrical system, operates the first and second switch circuits to regulate the generator output voltage and, in the alternative, to further reconfigure and/or deactivate the switch circuits based on their operating states. The generator maybe further coupled with an electrical energy absorbing device and the control device maybe further configured to operate on a switch, coupled with the electrical energy absorbing device, in response to a shutdown condition, RPM, rate of change of RPM, and voltage transient.

1. A vehicle electrical system, comprising:
(a) a generator coupled with an electrical load, said generator comprising a first field coil and a second field coil; (b) a first switch circuit coupled with the first field coil; (c) a second switch circuit coupled with the second field coil; and (d) a control device coupled with the generator, first switch circuit, and second switch circuit; wherein the control device is configured to: (i) ascertain an output voltage of the generator; (ii) ascertain operating states of at least one of the first and second switch circuits; (iii) apply one or more control signals to at least one of the first and second switch circuits to regulate the output voltage at a regulation voltage in response to the output voltage; and (iv) one of reconfigure and deactivate at least one of the first and second switch circuits in response to the operating states.
