Alternating current-direct current conversion device and electrical equipment

Abstract

The invention discloses an alternating current and direct current conversion device and electrical equipment. The device comprises a power supply module, a laminated busbar, a rectification module, and a heat dissipation module located below the rectification module, wherein the power supply module is divided into two sub-modules, and the two sub-modules are symmetrically arranged on two sides of the heat dissipation module and the rectification module; the rectification module is electrically connected with the power supply module through the laminated busbar. The modules in the device are simple and compact in arrangement mode and convenient to disassemble and assemble, and meanwhile the heat dissipation module connected with the rectification module in an attached mode is arranged, so heat dissipation efficiency of the device can be further improved.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to an AC / DC conversion device and electrical equipment. Background technique [0002] As one of the most widely used circuits in power electronics technology, the three-phase bridge rectifier circuit can convert alternating current into direct current to realize the functions of powering DC equipment and charging batteries. However, the working current of the rectifier circuit is large, and the heat generated in the working state is relatively large. The arrangement of electrical components in the existing AC-DC conversion device based on the three-phase bridge rectifier circuit is relatively complicated, which easily limits the heat dissipation performance of the rectifier circuit. , leading to poor heat dissipation effect of the device, which in turn affects the service life of electrical components. On the other hand, the complex spatial position structure also makes it...
