Natural Capacitor Voltage Balance in Multilevel Flying Capacitor Convertrs. a Review of Research Achievements*
The flying-capacitor (FC) topology is one of the more well-established ideas of multilevel conversion, typically applied as an inverter. One of the biggest advantages of the FC converter is the ability to naturally balance capacitor voltage. When natural balancing occurs neither measurements, nor additional control is needed to maintain required capacitors voltage sharing. However, in order to ...
متن کاملFlying capacitor multilevel PWM converter based UPFC
A unified power flow controller (UPFC) based on the flying capacitor (FC) multilevel voltage-source converter (VSC) topology with phase-shifted sinusoidal pulse-width modulation (PWM) control is presented. This converter allows higher power handling, potentially lower power loss, lower harmonic distortion and hence less filtering requirements when compared with the typical two-level counterppar...
متن کاملA Single Phase Multilevel Inverter with Novel Capacitor Voltage Balancing Technique
For medium-voltage power electronic applications, multilevel converters have become a popular option. While conventional twolevel converters utilize a direct series connection of switches to meet medium-voltage requirements, multilevel converters allow a higher voltage handling capability with reduced harmonic distortion and lower switching power losses. One of the most important requirements i...
متن کاملCapacitor Voltage Monitoring in Modular Multilevel Converter
A Modular Multilevel Converter (MMC) is an attractive solution for power conversion without transformers. As MMC consists of cascade connections and floating dc capacitors, it requires continuous voltage monitoring. An adaptive observer design has been presented to estimate the capacitor voltages from the measurement of arm currents. This work introduces a capacitance value of the cell capacito...
متن کاملComparison between flying capacitor and modular multilevel inverter
─ the paper describes the operational principle of flying capacitor and modular multilevel inverters. The detailed discussions of dc link capacitors voltage balancing methods for both inverters are given in order to enable fair comparison. The causes of dc link capacitors voltage imbalance in flying capacitor multilevel inverter with more than three levels are highlighted. Computer simulation i...
