Abstract

The invention provides a hybrid electric vehicle capable of realizing effective utilization and operation of inverters, which includes a motor-generator driven by an engine to generate alternating current, wherein the motor-generator is further configured to start the engine, a motor for driving the vehicle, a diode rectifier to rectify alternating current generated by the motor-generator, an inverter connected to a feed circuit between the diode rectifier and the motor to convert direct current in the feed circuit into alternating current, a power supply connected to a line connecting the diode rectifier with the inverter, a first feed circuit to supply current to the motor to drive the vehicle through the diode rectifier and the inverter in series a second feed circuit to connect the motor-generator with the power supply while bypassing at least the diode rectifier, and an alternating current converter provided in the second feed circuit.

Description

technical field [0001] The present invention relates to hybrid vehicles, and more particularly to hybrid vehicles suitable for series hybrid vehicles. Background technique [0002] The so-called series hybrid vehicle, as shown in Japanese Patent Laid-Open Publication No. Hei 11-220806 (hereinafter referred to as "Patent Document 1"), uses an internal combustion engine to drive a generator, and supplies electric power generated by the generator to an electric motor. The motor drives the drive wheels of the vehicle. A converter and an inverter are connected in series between the generator and the motor. The converter converts the primary current generated by the generator into a DC current, and then uses the inverter to convert the converted DC current back into an AC secondary. current, supplied to the motor. [0003] For example, in the series hybrid vehicle disclosed in Japanese Patent Laid-Open Publication No. 2005-204370 (hereinafter referred to as "Patent Document 2"),...
