エネルギーが除去できず、過電圧が発生した際の電気系統の回生部品のテスト。
Test with a source which does not act as a sink. Regenerative current < 10 mA. Current measurement must be made.

The DUT is connected to a powerful 4 quadrant amplifier and must be operated for at least t0 at U1.Thereafter,the activation of the feedback begins and at maximum regenerative current of the DUT, the decrease in the regenerative power abruptly (toff) must be terminated.
