Negative V
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
20; here we define the power switches and diodes of the inverter.
If the high-side switch (e.g., the IGBT Q1 in Figures 21 and 22) 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
DC bus voltage.
