Description

M438409 V. New description: [New technical field] This is a kind of AC/DC power device, especially an integrated AC/DC power device suitable for/from electric hybrid system. [Prior Art] Hybrid electric vehicle It has been developed for decades, and its power system can be mainly divided into series, parallel and series-parallel. In recent years, the integrated starter generator (Integrated Starter Genera (6), ISG) has gradually introduced vehicles to improve the pollution of the metropolitan area because of the low cost of the device and the simple structure. The main purpose is to start the motor and generator with the traditional fuel engine. The two units are combined, usually placed between the engine and the gearbox, and are controlled by appropriate drive to stop the fuel engine to replace the idling of the city. However, the hybrid system is converted by the high voltage alternator through the rectifier. 13⁄4 voltage DC. Due to safety issues, the battery needs to be a low-voltage energy storage device, so there is a problem of power flow conversion. It also includes technical issues such as generator control, buck DC converter control and power factor adjustment. In addition, when the integrated starter motor generator is used as the generator, the operating speed is usually 6000 卬m'. As the starting motor, since the starting torque of the car engine is usually 8 Nm, the difference between the two operating points is extremely large, so one liter is required. The DC-DC converter raises the battery's low voltage to a high voltage and then starts the motor through the driver. M438409 The creator is because of this in the spirit of active creation, thinking about one for oil and electricity. The integrated AC/DC power unit of the power system is used to improve the combustion efficiency of the grilling engine, reduce the hoarding of the power mechanism and the complexity of the device control. [New content] In view of the control and matching of power flow conversion between fuel engine, battery and motor. This creation integrates the generator, rectifier, step-down DC converter 'starter motor, step-up DC converter, starter motor driver and power motor driver as power output to be used in the hybrid electric power system. The fuel engine's combustion efficiency, reduced power mechanism volume, and complexity of device control can reduce the pollution generated by fuel locomotives in the metropolitan area and improve energy efficiency. To achieve the above objectives, the present invention provides an integrated AC/DC power device for a hybrid electric power system that utilizes power conversion between an engine and a battery unit to provide drive power required by a motor. The integrated parent DC power device includes a starting and generating unit, a power control unit, a converter unit, a voltage adjusting unit and a driving unit. The start-up and power generation unit is coupled to the engine 'and has a start mode and a power generation mode' to generate a power switching signal accordingly. The power control unit is coupled to the start-up and power generating unit to generate a power control signal and a power adjustment signal to generate power conversion according to the power switching signal to control the startup mode or the power generation mode. The converter unit is coupled to the starting and generating unit and receives the power control signal to thereby control the current flowing through the converter unit.
