Abstract

Quasi-two-level PWM operation of modular multi-level converters enables a significantly smaller amount of installed module capacitance, even with low output frequencies required for machine drives. This paper presents an implementation of this operation mode with an improved current control, which leads to fast and precise current transitions. The proposed current control is based on the combination of dead-beat control and predictive control, which are implemented using an FPGA. Experimental results on a laboratory prototype prove the feasibility of quasi-two-level PWM operation. The proposed current control is compared to the original one, showing an improved converter behavior.
