Modular Directed Series Multilevel Converter for HVDC Applications
Objective
The main objective of the project is to reduce switching losses caused by a large number of semiconductor (modular multilevel converter) switches.
Abstract
In this project, to mitigate switching losses and to reduce the size of the sub module capacitors in HVDC transmission systems, a modular directed series multilevel converter (MDSMC) is proposed. It is a hybrid topology having two main circuit components, namely, the chain-links consisting of a number of series-connected SMs and the director switches realized using a number of series connected insulated-gate bipolar transistors (IGBTs). A detailed analysis and operating principles of MDSMC are presented to highlight its important features.
The control and modulation schemes of MDSMC are presented that enable this converter to be utilized most effectively. The SMs capacitor size calculation is performed and compared with the major HVDC converters to validate its lowest capacitive energy storage requirement. Its ability to provide wide operating range and four-quadrant operation for HVDC application are also verified. Loss computation validates the ability of MDSMC to provide higher efficiency. A detailed comparison between MDSMC and other major HVDC converters is performed on the basis of their various structural parameters.
