Abstract:
1. An inverter test device, comprising: a test platform, used to carry tested inverters; a power supply-current detection unit, used to obtain a power supply-current signal I a load platform, used to carry one or multiple tested loads, wherein the input end of said load is coupled to the secondary side of said inverter, and the input end of said load is coupled to a signal channel Vch a power-control switch, coupled to and interposed between said power supply unit and the primary side of said inverter, and used to switch on/off the power for said inverter; a current/voltage detection unit, obtaining said consumed-current signal I a primary processing unit, responsible for the control of test process and the calculation of data processing, and having test programs, wherein said primary processing unit instructs said power supply unit, said power-control switch, and a multiplex selector via control lines to perform unbalanced current comparison, phase comparison, current/voltage deviation test, and fusion heat (I a signal converting unit, used to convert said power supply-current signal I the multiplex selector, controlled by said primary processing unit, being used to selectively transmit said power supply-current signal I
