6 FAQs about [High temperature test method for energy storage inverter]

How to test a high power three-phase grid-connected 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.

How to test an inverter?

Only energy corresponding to the losses is consumed. The test is done by circulating rated current within the three legs of the inverter. All the phase legs being loaded, the method can be used to test the inverter in both cases of a common or independent cooling arrangement for the inverter phase legs.

Why do inverters need burn-in tests?

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.

What is the maximum junction temperature error in a grid-connected inverter?

The corresponding estimated maximum junction temperature error is 1.09°C. A method to test a high power three-phase grid-connected inverter with LCL filter at its output is proposed. The method does not require a high power source or load. The power taken from the grid supplies only the losses in the SUT.

What is a regenerative configuration for inverter testing?

a Regenerative configuration for inverter testing where either an ac source or a dc source shown in dashed lines will supply the losses in the system b Regenerative configuration for UPS testing where only an ac source can be used for supplying the losses as both the input and output of the UPS are ac

How many traction inverters were tested?

Nine traction inverters were tested, which were divided into four groups with respect to the designed step-stress test profile. The changes in electrical and thermal indicators were observed online using the proposed monitoring system.
