The invention discloses a multi-inverter aging test system and test method based on a CAN network, and belongs to the field of inverter aging detection. The problems that an existing inverter aging platform cannot test multiple tested inverters at the same time and cannot analyze the consistency of the same time state of the multiple tested inverters are solved. The system comprises N test units and an upper computer. The upper computer communicates with the N test units through a CAN network; the upper computer is used for controlling the N test units in the same working time period, enablingeach test unit to work in a constant-power working state of one tested inverter corresponding to the test unit, and collecting the voltage, current and temperature output by the tested inverter in the constant-power working state, and an acquired result is uploaded to an upper computer to be displayed. The system is mainly used for carrying out the aging test on the inverter.
Description
technical field [0001] The invention belongs to the field of inverter aging detection. Background technique [0002] Inverter aging platform, the usual aging platform is used as a load-carrying resistive load, so that the output power of the inverter under test is completely converted into heat output. Its advantages are constant output and low price; however, its disadvantages are serious waste of power, The cost of aging is high, and the aging platform cannot test multiple inverters under test at the same time, and cannot analyze the consistency of the state of multiple inverters under test at the same time. Therefore, the above problems need to be solved urgently . Contents of the invention [0003] The purpose of the present invention is to solve the problem that the existing inverter aging platform cannot test multiple tested inverters at the same time, and cannot analyze the consistency of the same time state of multiple tested inverters. The invention provides a C...
