Abstract
An electronically controlled inverter type generator system driven by an engine includes first and second generating bodies that have respective first and second voltage generating characteristics in response to engine speed. The generator system selects the AC output from the first generating body when the engine is operated over a first range of engine speeds and selects the AC output from the second generating body when the engine is operated over a second range of engine speeds. The AC output from the selected generating body is rectified to a DC voltage, and the rectified DC voltage is converted to a controlled AC voltage. The use of two generating bodies enables the generator system to operate in an economy mode during normal load conditions and to be able to supply power to a greater load when needed.
