This example is based on a real industrial application in the field of Medium Voltage Drives (MVD).
It is very important to simulate the three-level inverter with all the semiconductors.
The inverter is tuned by a Direct Torque Control (DTC). The entire regulation has been implemented taking into account the real digital behavior, as implemented on a DSP (Digital Signal Processor).
The entire system has been modeled using more than 200 units to simulate in details the flux estimation, the DTC with multi-level hysteresis control, the switching frequency control and the speed control.
This example shows the potential of SIMSEN to simulate mixed signals. Simulation results present the step response behavior of the drive.
