Method for controlling electric motor drive device of engine, involves controlling amplitude of voltage supplied by direct current-direct current converter according to one of parameter representing speed of operation of engine

摘要

The method involves determining a parameter representing speed of operation of an engine (5), where rotational speed of the engine is measured during determination of the parameter. Intensity of magnetic flux generated at a rotor of the engine is controlled depending on the parameter representing the speed of the operation of the engine. Amplitude of voltage supplied by direct current-direct current (DC-DC) converter is controlled according to the parameter representing the speed of the operation of the engine. An independent claim is also included for an electric motor drive device of an engine.
