6.1 Typical Switching Losses

Because the EB1200-352J has integrated a DC bus capacitor bank, the worst-case commutation inductance (measured for
the switch with the longest path to the DC bus capacitors) is a constant 67 nH and does not vary from the setup used to
characterize switching characteristic.
