Record inverter testing data: During the inverter testing process, record various parameters, such as input/output voltage, current, power and waveform quality, in order to analyze the performance state of the inverter.
In this study, a novel method to test a high power three-phase grid-connected inverter is proposed. The method eliminates the need for high power sources and loads. Only energy corresponding to the losses is consumed. The test is done by circulating rated current within the three legs of the inverter.
Burn-in tests are used to ensure this. In inverters, thermal time constants can be large and burn-in tests are required to be performed over long durations of time. At higher power levels, besides increased production cost, the testing requires sources and loads that can handle high power.
Current regulation: Test the inverter's response to load changes to see if it can stabilize the output current during inverter testing. If the inverter cannot maintain stable output, the device may be damaged or the system may become unstable.
The inverter testing should be placed in a well-ventilated environment to ensure efficient inverter cooling or it may result in false inverter testing. When the heat dissipation system of the inverter cannot effectively dissipate heat, the performance parameters of the inverter may change abnormally.
