Three-Level Matrix Converter with Integrated Neutral-Point Potential Balancer
摘要
The multi-modular MC has the advantages of good output power quality and flexible expansibility, but a bulky transformer is necessary. Generally, the capacitor clamped MC utilizes flying capacitors to provide the middle voltage levels so as to produce multilevel output voltages. A drawback of the capacitor clamped MC is the need of excessive numbers of capacitors. Besides, complicated control methods would be required to balance the flying capacitor voltages.
