Abstract

The invention provides an electric integrated device of a vehicle-mounted charger and a vehicle-mounted DCDC, The electric integration device of the vehicle-mounted charger and the vehicle-mounted DCDC comprises a PFC module, a high-voltage AC side energy conversion switch module, a transformer module, a low-voltage DC side energy conversion switch module, a low-voltage DC side filter and protection module and a high-voltage DC side energy conversion switch module. A PFC module, a high-voltage AC side energy conversion switch module and a transformer module are connected in turn, that transformer module is connected with the low-voltage DC side energy conversion switch module and the high-voltage DC side energy conversion switch module, and the low-voltage DC side energy conversion switchmodule is connected with the protection module. The on-board charger and the on-board DCDC are electrically integrated by sharing electrical components. Compared with the on-board charger and the on-board DCDC, the on-board charger and the on-board DCDC save the volume occupied by the device, reduce the total weight and reduce the cost.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an electrical integration device of a vehicle-mounted charger and a vehicle-mounted DCDC. Background technique [0002] With the continuous development of electric vehicle technology, the trend of component integration is becoming more and more obvious. Integrated solutions can not only bring the advantages of function expansion to the vehicle, but also reduce the cost of the vehicle through the sharing of mechanical and electronic components. . The on-board charger is mainly used to draw electric energy from the 220V power grid, and after power conversion, the energy is charged into the high-voltage battery pack of the electric vehicle, while the on-board DCDC is used to convert the energy of the high-voltage battery pack of the electric vehicle into 12V battery energy. The integrated solution (Char Con) of (Charger) and vehicle-mounted DCDC (Converter) will be the mainstre...
