Abstract

The invention belongs to the technical field of transformers, and provides a vehicle-mounted transformer for new energy vehicles and a new energy vehicle. The vehicle-mounted transformer includes a transformer bobbin, two transformer cores inserted at two ends of the transformer bobbin, two inducer bobbins abutting against one end of each of the transformer cores respectively, two inducer cores inserted at one end of each inducer bobbin respectively, and a pedestal supporting and fixing the transformer bobbin and the inducer bobbins. Two first transformer windings isolated and insulated from each other are wound on the transformer bobbin in a parallel manner. An inducer winding is wound on each inducer bobbin. The tail lead of each inducer winding is connected to the head-end lead of the corresponding first transformer winding. Second transformer windings extending and fixed to the pedestal are clamped on two ends of the transformer bobbin respectively. The vehicle-mounted transformerovercomes a problem that vehicle-mounted transformers at present are low in the integration degree.

Description

technical field [0001] The invention belongs to the technical field of transformers, and in particular relates to a vehicle-mounted transformer for a new energy vehicle and a new energy vehicle. Background technique [0002] With the advancement of science and technology and the development of electronic technology, more and more electronic equipment needs to use transformer components. With the vigorous development of the electric vehicle industry, on-board electronic equipment is showing a trend of miniaturization, integration, and high power density. Especially the on-board OBC (On Board Charge) charger and on-board DC / DC, as the core components of electric energy conversion in the entire electric vehicle, urgently need miniaturization and high integration. [0003] In the prior art, an OBC power transformer and a DC / DC power transformer that are independent of each other are generally arranged inside the electric vehicle. In actual work, the OBC power transformer is use...
