Abstract
Circuits comprising at least one energy storage device, a resistor and switch arranged in series with the resistor are described. The energy storage device is arranged in parallel with the series connection of the switch and the resistor, and the switch is arranged to selectively switch the resistor into a parallel connection to the energy storage device. In some examples, the switch comprises a series connection of semiconductor switching elements. In some examples, the circuit may comprise a sub-module for use in a multilevel modular converter.
