Abstract

The invention provides a vehicle-mounted power electronic integrated device, which comprises power modules, a first contactor, an alternating current power supply and a vehicle-mounted high-voltage storage battery, and is characterized in that the number of the power modules is positive integer multiples of 3; wherein each power module comprises an AC/DC power full-bridge unit and a DC/DC conversion unit which are connected with each other, the AC/DC power full-bridge unit in each power module is connected to the alternating current power supply, and the DC/DC conversion unit in each power module is connected to the vehicle-mounted high-voltage storage battery; and the AC/DC power full-bridge unit in each power module is connected to the first contactor, and vehicle-mounted electrical integrated control is carried out through the first contactor. The size of the vehicle-mounted power electronic integrated device can be effectively reduced, and multifunctional integrated control of thevehicle-mounted power electronic integrated device on vehicle-mounted equipment can be achieved.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a vehicle-mounted power electronics integration device. Background technique [0002] At present, it is common for automobiles to use multiple power sources at the same time. Through power electronics technology, different functions in automobiles can maximize their own effects. For the vehicle-mounted power electronic devices involved in the power chain of electric vehicles and hybrid electric vehicles, multiple vehicle-mounted power electronic devices can be integrated to reduce system size and save energy due to the consideration of the internal space and control requirements of the vehicle itself. Harness and reduce costs. [0003] In the existing integration scheme of on-board power electronic devices, two or more power electronic devices are usually installed in the same casing or in a cooler, and there is no direct coupling and correlation in control between eac...
