Abstract
The present invention discloses an inverter energy-stream circulation testing device comprising a DC power supply, a trialed inverter, an inductor, a voltage sensor, a current sensor, a PWM rectifier and a control cabinet, all of which are assembled to realize the testing functions of the inverter. Each cabinet of the device is fixed on the ground, the trialed inverter is fixed on a testing platform, the inductor is arranged on an inductance platform, the main circuit of the PWM rectifier is arranged in an AC cabinet via an iron rack; the AC end of the trialed inverter is connected with one end of the inductor, the DC end of the converter is connected with the output end of a DC power supply; the AC end of the PWM rectifier is connected with the other end of the inductor, the DC end of the PWM rectifier is connected with the output end of an AC power supply; the DC sides of two converters, where one is tested and another is loaded, are connected with each other; the AC end of the DC power supply is connected with the electrical source. The device resolves the problem that converter testing platform is as usual characteristics of huge electric consumption with loading, loud noises and the need for the DC power supply with large power.
