**5.3 IPC method and SCC method with IVR technique**

The generation of a pulse to trigger the RCC, duty cycle variation, and the output power (Po) variation during regeneration for the IPC method with the IVR technique is shown in **Figure 19**. **Figure 20** shows input phase powers (PA, PB, PC) of MC drive after regeneration control. From simulation results, the IVR technique for both methods (IPC and SCC) is producing acceptable results to avoid regeneration with a MC drive similar to PC technique.
