Abstract :
Dc-link capacitor voltages must be actively controlled in Multi-Point-Clamped (MPC) converters, in order to achieve a correct voltage sharing. This work demonstrates that when a MPC Active Front End (AFE) rectifier feeds a MPC inverter a balancing strategy does exist that is able to guarantee a correct functioning in all operating conditions. The analytical work, which has been performed to determine the theoretical limits related to a correct behavior, is presented. In addition, a balancing control strategy that has been based on the developed theory is described.
