occurs to the insulation layers due to the partial discharge. Consequently, this test is not
performed at CONCEPT as a series test. Where repeated insulation tests (e.g. module test,
equipment test, system test) are run, the subsequent tests should be performed at a lower test
voltage: the test voltage is reduced by 400 V for each additional test. The more modern if more
elaborate partial-discharge measurement is preferable to such test methods as it is almost entirely
non-destructive.
The partial discharge test is performed for each driver within the scope of series production. This
constitutes a high voltage testing rate of 100% in series production.
The supported gate charge refers to the stability of the power supply voltages and to the dynamic
voltage drop at the supply rail. Exceeding the maximum supported gate charge may lead to
malfunction or thermal overload of the gate drivers. The customer may increase the specified
maximum value of the supported gate charge by connecting additional supply capacitors between
terminals Cs and COM up to a total of 100μF. External blocking capacitors must be applied for
pulse gate charges >5.1μC. The capacitance rating must be greater or equal 2μF per 1μC gate
pulse charge exceeding 5.1μC. Place the capacitors with short traces to the IGD616’s pins. Make
sure to check your design for the thermal limits given in note 2.
