  • Chain-link modules for voltage source converters
    Patent number: 12003169
    Abstract: In the field of chain-link modules for voltage source converters, there is a need for an improved chain-link module. A chain-link module, for connection in series with other chain-link modules to form a chain-link converter selectively operable to provide a stepped variable voltage source within a voltage source converter, includes at least one pair of series-connected switching elements that are connected in parallel with a number of series-connected energy storage devices. Each energy storage device has an auxiliary power supply unit connected in parallel therewith to source energy therefrom for supply to an auxiliary chain-link module control circuit. The chain-link module also includes a modulation controller which is interconnected between each auxiliary power supply unit and the auxiliary chain-link module control circuit. The modulation controller is configured to modulate the proportion of energy supplied to the auxiliary chain-link module control circuit by each auxiliary power supply unit.
