IRS21867S
Tolerant to Negative V S Transients
A common problem in today’s high-power switching converters is the transient response of the switch node’s voltage
as the power switches transition on and off quickly while carrying a large current. A typical 3-phase inverter circuit is
shown in Figure 8; here we define the power switches and diodes of the inverter.
If the high-side switch (e.g., the IGBT Q1 in Figures 9 and 10) switches off, while the U phase current is flowing to an
inductive load, a current commutation occurs from high-side switch (Q1) to the diode (D2) in parallel with the low-side
switch of the same inverter leg. At the same instance, the voltage node V S1 , swings from the positive DC bus voltage
to the negative DC bus voltage.

Also when the V phase current flows from the inductive load back to the inverter (see Figures 11 and 12), 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.
