IRS2334SPbF/MPbF
The measured characteristic of the advanced input filter is shown in Figure 12. On the left side the characteristic
for narrow ON pulses is shown (short positive pulse) while on the left side the characteristic for narrow OFF
pulses is shown (short negative pulse). The x-axis represents the input pulse duration PW IN , while the y-axis the
resulting output pulse duration PW OUT . For pulses with input pulse duration PW IN less than the filtering time t FILIN
the resulting output pulse duration PW OUT is zero because the filter rejects the input signal. For pulses with input
pulse duration PW IN greater than the filtering time t FILIN the resulting output pulse duration PW OUT tracks the input
pulse durations well, the higher the duration the better the symmetry.
Figure 12: Measured advanced input filter characteristic
The difference between the output pulse duration PW OUT and the input pulse duration PW IN of both the narrow
ON and narrow OFF cases is shown in Figure 13. The x-axis represents the input pulse duration PW IN , while the
y-axis the resulting difference PW OUT –PW IN .

Tolerant to Negative VS Transients
A common problem in today’s high-power switching converters is the transient response of the switch node’s
voltage as the power devices switch on and off quickly while carrying a large current. A typical 3-phase inverter
circuit is shown in Figure 14; where we define the power switches and diodes of the inverter.
If the high-side switch (e.g., the IGBT Q1 in Figures 15 and 16) 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.
