Also when the V phase current flows from the inductive load back to the inverter (see Figures 28 and 29), and Q4
IGBT switches on, the current commutation occurs from D3 to Q4. At the same instance, the voltage node, V
S2
,
swings from the positive DC bus voltage to the negative DC bus voltage.

However, in a real inverter circuit, the V
S
voltage swing does not stop at the level of the negative DC bus, rather it
swings below the level of the negative DC bus. This undershoot voltage is called “negative V
S
transient”.
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
C
and L
E
for each IGBT. When the high-side switch is on,
V
S1
is below the DC+ voltage by the voltage drops associated with the power switch and the parasitic elements of
the circuit. When the high-side power switch turns off, the load current momentarily flows in the low-side
freewheeling diode due to the inductive load connected to V
S1
(the load is not shown in these figures). This current
flows from the DC- bus (which is connected to the COM pin of the HVIC) to the load and a negative voltage between
V
S1
and the DC- Bus is induced (i.e., the COM pin of the HVIC is at a higher potential than the V
S
pin).
