However, in a real inverter circuit, the V
swings below the level of the negative DC bus. This undershoot voltage is called “negative V
The circuit shown in Figure 30 depicts one leg of the three phase inverter; Figures 31 and 32 show a simplified
illustration of the commutation of the current between Q1 and D2. The parasitic inductances in the power circuit from
the die bonding to the PCB tracks are lumped together in L

In a typical motor drive system, dV/dt is typically designed to be in the range of 3-5 V/ns. The negative V
voltage can exceed this range during some events such as short circuit and over-current shutdown, when di/dt is
greater than in normal operation.
International Rectifier’s HVICs have been designed for the robustness required in many of today’s demanding
applications. The IRS26310D has been seen to withstand large negative V
V for a period of 50 ns. An illustration of the IRS26310D’s performance can be seen in Figure 33. This experiment
was conducted using various loads to create this condition; the curve shown in this figure illustrates the successful
operation of the IRS26310D under these stressful conditions.
