I'm new on DSP C2000 F28335 (based on the TMS320F28335) and I'm working on a project to implement a simple algorithm three phase sine wave pulse width modulation (SPWM) in order to control a three phase inverter plugged into an asynchronous machine. The purpose of this experiment is to vary the speed of the machine using the input frequency.

So I developed the whole system in Matlab/Simulink and then I generate the C code from the model to the DSP target. But the machine won't work, the output voltage seems to be fine, but the current is too high, at first I thought that it's a normal spike due to the high input speed reference, so I increased the speed gradually, but the same thing happened again the current goes too high and the machine gives an alert beep.
