IRS211(7,71,8)(S)
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 half bridge
circuit is shown in Figure 5; here we define the power switches and diodes of the inverter.
If the high-side switch (e.g., Q1 in Figures 6 and 7) switches off, while the current is flowing to a load, a current
commutation occurs from high-side switch (Q1) to the diode (D2) in parallel with the low-side switch of the
inverter. At the same instance, the voltage node V S swings from the positive DC bus voltage to the negative
DC bus voltage.

Also when the current flows from the load back to the inverter (see Figures 8 and 9), and Q2 switches on, the
current commutation occurs from D1 to Q2. At the same instance, the voltage node V S swings from the positive
DC bus voltage to the negative DC bus voltage.
