Abstract

The invention relates to an alternating current / direct current energy reclaiming type electronic simulation loading device and a control method of the alternating current / direct current energy reclaiming type electronic simulation loading device. The alternating current / direct current energy reclaiming type electronic simulation loading device is composed of a controller, an input side transform unit, an input side H-bridge inversion unit, an isolation high-frequency transformer, an output side H-bridge rectifying unit, an output side conversion unit, a display unit, an input voltage mutual inductor, an input current mutual inductor, an output voltage mutual inductor, an output current mutual inductor, a direct current voltage mutual inductor, an input alternating current terminal, an output alternating current terminal and an output direct current terminal. The alternating current / direct current energy reclaiming type electronic simulation loading device is an energy feedback electronic simulation loading device, and can output feedback to an alternating current or direct current power supply, and the input side can simulate three modes of constant power, constant current and constant impedance; and besides, the alternating current / direct current energy reclaiming type electronic simulation loading device can simulate various load characteristic curves and has adjustable power factor, and the device can be set by a display unit panel or by an upper computer through communication. The loading testing study is remarkably advantageous in electricity saving, and has the characteristics of flexibly simulating various loading characteristics and realizing alternating current / direct current feedback.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to an AC / DC energy feeding electronic analog load device and a control method thereof. Background technique [0002] With the increasingly widespread application of power electronic devices, there are more and more new products and new technologies. At present, various power electronic device factory tests and reliability tests before use (mainly aging tests) generally use the method of resistive energy discharge to conduct physical experiments, and it is difficult to test and test other load characteristics. To overcome this problem, it is necessary to test by electronically simulating a power load. It is an experimental device designed and realized by using power electronics technology, computer control technology and power system automation technology, and is used for checking and testing various DC power supplies. [0003] The difference between this design and the g...
