Description

technical field [0001] The invention relates to the field of automotive electronic equipment, in particular to an Inverter, DCDC and OBC deeply integrated module suitable for XEV. Background technique [0002] At present, the increasingly prominent environmental problems, rising oil prices and the promotion of national policies have promoted the rapid development of new energy vehicles. More and more people choose new energy vehicles as a means of travel. With the popularity of new energy vehicles, financial subsidies are gradually reduced, which makes OEMs face huge cost challenges. [0003] In order to cope with the market challenges after the government subsidy decline, OEMs need to optimize all components. How to improve system integration and further reduce production costs under the premise of ensuring performance has become an important research direction for various auto parts suppliers. As an important part of new energy vehicles, Inverter is the power electronic...
