ABSTRACT:
An object of the invention is to maintain high vehicle driving performance and system efficiency by preventing reductions in the traction characteristic and the maximum driving speed of a vehicle.The invention relates to an electrical system for an electric automotive vehicle for driving the vehicle by supplying an electric power of a direct-current power supply to an electric motor for driving wheels via a semiconductor power converter for driving the wheels such as an inverter and speed-variably driving this electric motor or an electrical system for an electric automotive vehicle using an engine and a direct-current power supply as driving sources. A booster chopper200is connected between a battery device1or4as the direct-current power supply and an inverter2or a semiconductor power converter100, and is controlled so that a direct-current input voltage of the inverter2or the like becomes substantially constant.
