Problems solved by technology

However, if this method is adopted, there is a problem that the motor cannot be driven even when the motor is started when the engine is started.
[0008] On the other hand, in the operating state of the vehicle, the capacity required by the inverter varies greatly. Therefore, in the operating region where the output power is much lower than the rated value, the inverter load factor decreases according to the load factor of the inverter. The efficiency of the inverter itself is also reduced to a corresponding extent, so there is still the problem that the inverter cannot be used efficiently

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"),...
