Problems solved by technology

[0011] However, the current burn-in equipment of the existing AC / DC converter is mainly to feed the electric energy into the mains in the form of AC. In addition to using an additional DC / AC converter, the design of the circuit and the controller is also relatively complicated. Low power recovery rate

Embodiment Construction

[0027] Figure 5 It is a structural schematic diagram of a burn-in test device according to an embodiment of the present invention. Depend on Figure 5 It can be seen that the structure of the burn-in test equipment includes an AC / DC converter (504) and an active electronic load (520), wherein the AC / DC converter (504) can be a full-bridge rectifier converter, and the active electronic load (520) is a DC / DC converter.

[0028] The AC / DC converter (504) mainly utilizes full-bridge rectification to convert the externally supplied commercial power from the AC power of the AC power supply (502) to DC power, and then supplies the DC power to more than one converter to be tested (511-518) The input terminal (a, b) of the test converter (511-518) flows into the current, and then is stabilized by the input capacitor inside the test converter (511-518).

[0029] In order to simultaneously test multiple sets of converters to be tested (511-518) and reduce the burn-in test time, an e...

Abstract

An electric-energy recyclable burn-in test device comprises an alternating current / direct current converter, a test block, an active electronic load and an electric-energy recycling line. An input end of the alternating current / direct current converter is connected to an alternating current power supply; the test block is used for arranged more than one converter to be tested, and an input side of the test block is connected to an output end of the alternating current / direct current converter; an input end of the active electronic load is connected to an output side of the test block for providing load characteristic simulation for the more than one converter to be tested; and the electric-energy recycling line is used for connecting an output side of the active electronic load with the input side of the test block to send electric energy from the output side of the active electronic load back to the input side of the test block for electric energy recycling.

Description

technical field [0001] The invention relates to a burn-in test device, in particular to a burn-in test device for a power converter capable of recovering electric energy. Background technique [0002] In the fierce business competition, the products of power converter manufacturers not only need to meet the technical specifications, but also need to maintain high reliability and high quality. Failure to detect poor-quality products before they leave the factory will seriously affect goodwill and increase losses. Therefore, the power converter manufacturer will conduct a burn-in test before the product leaves the factory. [0003] In addition to maintaining product quality, many countries and large international companies have actively promoted carbon footprint labels, and required manufacturers and their supply chain manufacturers to provide carbon footprint labels. Therefore, in order to compete in the market in the future, excellent technology and In addition to product ...
