Abstract

The invention discloses a DC / DC converter, and the converter comprises a plane transformer, a high-molecular solid capacitor, and a housing. The interior of the inner cavity of the housing is provided with an accommodation part which is used for accommodating the plane transformer and the high-molecular solid capacitor. The top of the housing is provided with first cooling fins which are arranged in a left / right direction, and a cooling fan is disposed above the first cooling fins. The converter employs the plane mirror to avoid the hidden troubles of turn-to-turn short circuit, employs the high-molecular solid capacitor to improve the performance of high temperature resistance, and improves the heat dissipation performance and stability through the cooling fan and the first cooling fins.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a DC / DC converter. Background technique [0002] DC / DC converters can convert one DC voltage into other DC voltages, and are widely used in mobile phones, MP3, digital cameras, portable media players, automobiles and other fields. The current DC / DC converters generally use ordinary transformers, which have the risk of inter-turn open circuit, and the capacitors are generally electrolytic capacitors, which have large dielectric loss and capacity errors, and poor high temperature resistance. Contents of the invention [0003] The purpose of the present invention is to propose a DC / DC converter, which avoids the hidden danger of inter-turn open circuit, improves high temperature resistance performance, and improves heat dissipation performance and stability. [0004] For reaching this purpose, the present invention adopts following technical scheme: [0005] A DC / DC conve...
