Title: ELECTRICAL GENERATOR EMPLOYING ROTARY ENGINE
Abstract:
A system for generating electrical power signals from a fluid fuel source (30). The system comprises an engine (22) and a generator (24). The engine (22) burns the fuel and is connected to the generator (24) such that the generator (24) generates a raw power signal. An output stage (28) generates an output signal from the raw power signal. A control circuit (26) controls the operation of the engine (22) based on the output power signal. The control circuit (26) further controls the operation of the engine (22) based on an output current of the generator (24) when this output current exceeds a current threshold level. The control circuit (26) additionally controls the operation of the engine (22) based on a temperature of the engine (22) when the engine temperature exceeds a rated temperature level. The system thus generates sufficient power to supply a variable load but stays within an operating range defined by a rated power level and the rated temperature level.
