Abstract

An important step in Voltage-Source Modular Multilevel Converter (MMC) design is the selection of adequate semiconductor blocking voltage class. This paper highlights that particularly for grid connected medium voltage applications, the choice of suitable switch blocking voltage class is not so straightforward. The market available switch voltage ratings results in a discrete integer relationship for the number of submodules (N) with a fixed dc link voltage. This is shown to introduce interesting design trade-offs in consideration to investment costs, required capacitance for reasonable ripple voltage, submodule redundancy requirements, conduction switching losses. Using the example of a 10 MVA half bridge MMC connected to a 10 kV grid, it is shown that 1.7 kV and 3.3 kV insulated gate bipolar transitors (IGBTs) can be possible choices as compared to 1.2 kV, 4.5 kV and 6.5 kV blocking voltage.
