Test cell for inverter testing

Contacting and safety-compliant test housing.

The project

We were able to support our partner IRS Systementwicklung GmbH in designing test cells for inverters for a well-known OEM. In this project, AUTFORCE designed and built the test object fixture with contacting and water conditioning for up to four test objects operated in parallel. Connection panels were installed for two test objects per test cell.

This configuration can be used for continuous operation applications as well as for development-related tests. Variations and our customers’ own ideas are always welcome.

Keyfacts

  • Two 3-phase or one 6-phase inverter
  • Customized design of the test cell
  • ESD and safety-compliant housing
  • Integrated multi-channel cooling water supply

Realization

The test cell has the AC, DC and signal contacts of the inverter in the back area. The inverters can either be placed loosely on the drainage channel or fixed in place using a mounting plate. In this project, a four-circuit water conditioning system was installed in one of the two CUBEs for the secondary circuits of the inverters. This has an integrated emptying system using compressed air. The accuracy of the flow control was crucial in this project. Tests were carried out in advance with conventional pumps and gear pumps.
