Detailed Description
A driving power take-off power generation system comprises an ISG generator, a power converter, a DC/DC converter, a power manager and a battery;
the rotor of the ISG generator is directly connected with the transmission shaft of the automobile engine and the transmission case, and the output interface of the ISG generator is connected with the input interface of the power converter to provide electric energy for the power converter;
the power converter comprises a rectifying module, a voltage stabilizing module and an inverter, the power converter synchronously rectifies input alternating current into direct current through the rectifying module, and after the direct current is stabilized by the voltage stabilizing module, the output of the power converter is divided into two parts, the first part directly outputs the direct current to be supplied to the DC/DC converter to provide the direct current for a direct current load, and the second part is converted into stable alternating current through the inverter to supply power for the alternating current load and charge the battery under the conditions of surplus output power and battery feed;
the battery power supply line is connected with the DC/DC converter DC power supply line in parallel to supply power for the DC load, and the conversion is realized through the power supply manager.
Furthermore, the driving power takeoff power generation system also comprises a display control module which is used for controlling the power converter to be turned on and off, and simultaneously displaying the state parameters and the alarm display of the power converter.
Optimally, the output voltage of the ISG generator under the normal operation state is AC 150V-600V.
Preferably, the alternating current output by the power converter is AC230V, 50HZ and not lower than 14KW alternating current.
Further, the direct current output by the power converter is DC 500V.
Further, the DC/DC converter and battery provide DC28V/4KW direct current for the direct current load.
The working principle of the invention is as follows: under the normal operation state of the generator (output voltage AC150V-600V), the generator is used as the input of the power converter to provide electric energy for the power converter, the power converter converts the input alternating current into direct current through synchronous rectification, the direct current is stabilized through the voltage stabilizing module, and the stable alternating current is output through the inverter.
The output of the power converter is divided into two parts, wherein one part outputs AC230V and 50HZ alternating current which is not less than 14KW alternating current, and the power converter is mainly used for supplying power to an alternating current load and charging a battery under the conditions of surplus output power and battery feed; the other part of the direct current is DC500V and is supplied to a DC/DC converter to output DC28V/4KW direct current, so that the direct current can meet the use of vehicle-mounted communication equipment or terminal equipment with higher power supply requirements.
If the vehicle brakes at a low speed and in a short time during the running process, and the output voltage of the generator is lower, but the wide voltage input range of the power converter ensures that the power converter system can output power not lower than the power in a rated state, and ensures that the electric equipment can run reliably. Under the condition that an engine of the chassis suddenly shuts down, a direct current load powered by the DC/DC converter can be seamlessly switched to be powered by the battery system through the power manager, the battery system can provide DC28V/4KW of output power for not less than 30min, and data storage and peripheral safety processing are guaranteed.
In summary, the driving power take-off power generation system protected by the invention can output direct current and alternating current with stable and high quality, meets the use requirements of vehicle-mounted communication equipment or terminal equipment with high power supply requirements, and can be seamlessly switched to a battery system for short-time power supply under the condition that an engine suddenly shuts down.
