Abstract

The invention provides a DC-DC converter and an electronic device using the same. The DC-DC converter comprises a transformer, a first inductor and a second inductor, wherein the transformer comprises a plurality of first voltage transformation modules, a second voltage transformation module and two first magnetic cores; wherein each first voltage transformation module comprises a primary winding and a secondary winding; the second voltage transformation module comprises a primary winding; the second voltage transformation module and the plurality of first voltage transformation modules are sequentially sleeved between the two first magnetic cores; the first inductor and the second inductor are arranged on the two sides of the transformer; the first inductor comprises a first winding, and the first winding is connected with the plurality of primary windings; and the second inductor comprises a second winding, and the second winding is connected with the secondary winding. The DC-DC converter provided by the invention is better in performance and better in inductance value, withstand voltage value and safety value.

Description

technical field [0001] The present invention relates to the technical field of transformers, in particular to a DC-DC converter and an electronic device using the DC-DC converter. Background technique [0002] A DC-DC converter (DC-DC) is a DC conversion device that converts a DC voltage into another DC voltage. The DC-DC converter is one of the important components in the design of switching power supply. With the rapid development of electronic power technology, switching power supply has been widely used in many fields such as computer, communication and railway, and has achieved remarkable economic benefits. With the development of rail transit and new energy industries, the requirements for the installation and use environment of DC-DC converters are getting higher and higher, and the requirements are compact structure, high reliability, low cost and easy installation. However, the performance and safety regulations of existing DC-DC converters are still difficult to ...
