Abstract

The invention relates to the technical field of DC-DC convertors of chargers, in particular to a transformer of a high-power charger of a new energy electric vehicle. The transformer comprises a framework and magnetic cores matched with the framework, the two magnetic cores are cooperatively installed on the framework side by side, and the framework comprises an upper mounting block and a lower mounting block; a hollow square cylinder is arranged between the upper mounting block and the lower mounting block through supporting, through grooves communicated with the square cylinder are formed inthe upper mounting block and the lower mounting block, and the magnetic cores correspond to the upper mounting block and the lower mounting block respectively, penetrate through the corresponding through grooves and then are placed in the square cylinder for cooperation. The transformer is simple in structure, low in manufacturing cost, large in magnetic flux and high and stable in output power of the charger.

Description

technical field [0001] The invention relates to the technical field of DC-DC converters for chargers, and the specific field is a transformer for high-power chargers for new energy electric vehicles. Background technique [0002] The charger provides stable power output for electronic equipment, its performance directly determines the quality of electronic products, and the performance of the charger is closely related to the design of the transformer. It can be said that the transformer plays a key role in the charger and determines the key technical indicators and working status of the circuit. Therefore, for most chargers, the design of the charger is ultimately the design of the transformer. [0003] The transformer plays the function of voltage conversion in the circuit, and also has the functions of insulation isolation and power transmission. The transformer and switch tube of the charger together form a self-excited intermittent oscillator, thereby modulating the in...
