Evaluation Kit EASYKIT AUX DRIVES (FS50R07W1E3_B11A)
The passive tests are followed by switching tests of low side switches (see Figure 14) and high side switches
(see Figure 15). Each switch is turned-on and Vce voltage, low side phase current, DCL voltage, and gate
driver fault condition is checked for proper values. After this the switch is turned-off again.
After the test is successfully passed the default condition is than all low side switches turned-on. This
enables the supply of the high side gate drivers, which are implemented via bootstrap supply.
The same test procedure of the low side switches is than performed with the high-side switches, whereby the
corresponding low side switch is turned-off before.
