Description

Technical Field

[0002] With the development of power electronics technology, an energy feedback type electronic load is a new type of power electronic device used for the factory tests of various power supplies and capable of simulating the characteristics of actual resistive loads. The energy feedback type electronic load can not only simulate various load characteristics, but also return electrical energy to the power grid without pollution, which is an inevitable trend in the development of current electronic loads. Compared with ordinary resistive loads, its working mode is to recycle the output energy of the power supply under test by using power electronic conversion technology on the premise of completing the test power experiment and test, which not only saves energy but also does not generate a large amount of heat, avoiding the problem of the environmental temperature rise in the test site. Since the test power of this electronic load system is not converted into heat energy, there is no need to use a large-sized resistance box and cooling equipment, saving the installation space and reducing the environmental noise.
