It is also necessary to prevent excessive load current from pulling the IGBT out of saturation. The dissipation will rise to high levels that can destroy the device in a relatively few microseconds. The designer must balance the need to limit dissipation with the need for voltage protection by controlling the rate of gate signal turn-off. Lest one conclude from the above that the IGBT is a fragile device, nothing could be further from the truth.
IGBTs have proven themselves as the power conversion elements in AC motor drives over 20, hp and in choppers for DC electric arc furnaces at power levels above MW. They are rugged, reliable devices.
F our IGBTs can be combined to form a bipolar switching circuit that is the basis for many motor drives and other applications. Figure 3shows the basic H-bridge.
The IGBTs are each equipped with an antiparallel diode that provides a free-wheeling path for load current and clamps any switching transients to the DC buses. If 3 and 4 are on, the current flows in direction R. Both polarities can be pulse width modulated to form an AC output waveform.
If a sine wave is used as a command waveform, the switching series is shown in Fig. The output waveform is sometimes cleaned up with an output filter to lessen harmonics at the load. One more section can be added to this circuit to form the threephase motor drive shown schematically in Fig. Many variations on the three-phase circuit have been devised to meet the objectives of lower harmonic distortion at the load, higher voltage output, and a host of other specialized needs.
Among these circuits is the neutral-point-clamped inverter, an arrangement that offers five switching voltage levels instead of only two.
