Abstract

The invention discloses a DC / DC converter for a high-speed electric vehicle and a consolidation circuit for a vehicle-mounted charging machine. A charging machine circuit and a DC / DC conversion powersupply circuit are included, the charging machine circuit comprises a full bridge switch circuit and a main transformer, an output end of the main transformer is provided with a full bridge rectifyingtube, the DC / DC conversion circuit comprises a first-stage BUCK circuit and a full pulse-duration push-pull circuit which is composed of a pair of MOS switching tubes and the main transformer, namelyan intermediate tap is arranged at an output winding group of the charging machine. According to the converter and the charging machine, a switch is converted according to OBC and DC states, the purpose of the combination of a shared main transformer is achieved, the cost of a vehicle-mounted integrated power supply is optimized, and there exists no influence on other functions and indicators ofthe circuit.

Description

technical field [0001] The invention relates to the field of vehicle power supplies, in particular to a combined circuit for a DC / DC converter and a vehicle charger for a high-speed electric vehicle. Background technique [0002] In pure electric vehicles, the on-board charger OBC and DC / DC conversion power supply are two important electrical components. It will be a future trend to install two sets of independent electrical design components in the same housing. This method is simple in principle and can save structural parts and some wiring costs, and has begun to be recognized by vehicle manufacturers. The design of circuit integration can further optimize the number of internal electronic parts, further reduce the overall cost, and facilitate structural design. However, in the prior art, the reliability of the operation of the combined circuit under the two working conditions, the guarantee of technical indicators, and the non-conflict between them need to be resolved. ...
