Figure 49. Top and Bottom Arm Waveforms
Typical Verification
Figure 49 represents how a typical verification can be conducted in a circuit configuration as shown in
Figure 47 and in waveform observations in Figure 48. This example is based on a 600 V, 300 A IGBT
module and has been observed with the control signal phase of the top arm changed. Figure 49 (1) shows the
no short-circuiting situation, while Figure 49 (2) reflects the short-circuited top and bottom arms condition.
