Alternator and regulator for use therewith

摘要

A regulator is disclosed for regulating a DC power supply such as an automotive alternator or generator which has a wide speed range and is hence capable of producing an output voltage and power which varies between wide limits. The regulator comprises electronic circuitry which allows the voltage at the alternator to rise while limiting the current therethrough, typically by means of pulse-width modulation; a DC-DC converter connected to the load; and circuitry to control the output voltage of the DC-DC converter within close limits. A permanent magnet alternator provided with a regulator of the type described is also disclosed.
