Power module aging device

Abstract

The invention discloses a power module aging device, which comprises an aging box. The aging box is divided by an insulated separator plate into a lower aging test circuit and an upper power fixationmechanism. The power fixation mechanism comprises a fixation bottom plate. The four corners of the fixation bottom plate are respectively provided with a telescopic support frame. The upper surface ofthe fixation bottom plate is provided with a slide guide. The two ends of the slide guide are internally and vertically embedded by a spring fixation plate. The top end of the spring fixation plate is embedded by a wiring column. The aging test circuit comprises a core controller and a power supply battery. The core controller is connected with a battery management chip. A GPIO port of the core controller is connected with a voltage stabilization transformation module through a wire. The input end of the voltage stabilization transformation module is connected to the output end of the power supply battery and outputs an electric signal to the wiring column. The driving end of the core controller is connected with an electric heating pipe. The power module aging device is small in size andconvenient to move and accommodate, can carry out real-time adjustment according to a power supply under test, is high in environment adaptability and is simple, safe and convenient to use.

Description

technical field [0001] The invention relates to the field of power testing equipment, in particular to an aging device for a power module. Background technique [0002] The aging test project refers to the process of simulating the various factors involved in the actual use conditions of the product to carry out corresponding condition strengthening experiments on the aging of the product. The aging of the power supply refers to simulating a test environment under high temperature and harsh conditions. High-performance electronic products are burned for a long time to improve the production process of product safety, stability and reliability. Nowadays, the aging of power supplies is generally carried out in professional aging rooms. The aging room, also known as the burn-in room, is aimed at the simulation of high-performance electronic products (such as: complete computer, display, terminal, automotive electronic products, power supply, motherboard, monitor, switching char...

Problems solved by technology

[0003] Existing aging rooms generally require special sites to be built and operated by professionals. The aging rooms occupy a large area, have high maintenance costs, and are troublesome to operate. For laboratory operations of some small mobile power supplies, such aging rooms are obviously too cumbersome , does not meet the requirements of low power consumption and low cost
