I was looking into solutions for a 3 phase active rectifier (rectification and power correction) using IGBTs. The topology is exactly the same as for a motor inverter. TI seems to have a kit for C2000 doing this, but there is no example for it (found one somewhere on the net, but not very well documented).
It might be a stupid idea, but what if one would connect a 3 phase mains power directly into motor output of an InstaSPIN based inverter? (through three inductors, one for each phase). For the motor controller this would look like a 3 phase induction motor spinning exactly at 50Hz. Then in a Torque controller mode one would command a negative torque - provided that voltage feedback and current feedback works correctly, the DC current should start flowing from the inverter's DC bus. If one would implement a control loop that maintains a constant DC bus voltage by commanding torque value, it should result into a PFC rectifier.
Do you see any issue with this approach?
