Description

technical field

[0001] The invention relates to a multi-input modular high-frequency isolated single-phase electric energy feedback type electronic load, which is mainly used for full-load aging detection of modern switching power supplies such as communication power supplies, computer power supplies and electric power supplies. technical background

[0002] At present, the full-load aging detection of various switching power supplies mostly uses resistive loads. The main defect of this kind of load is that the resistance will consume all the DC power used for detection, resulting in a lot of energy waste. In addition, different power supplies need to be replaced when testing different power supplies. Resistors are also inconvenient to use. Contents of the invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-input channel modular high-frequency isolated single-phase electric energy feedback type electr...
