SUB-MODULE OF A MODULAR BRAKING UNIT, BRAKING UNIT, AND METHOD FOR OPERATING THE BRAKING UNIT

A sub-module of a modular braking unit that is connected to a DC transmission network. Each sub-module has an inverse diode, and a storage capacitor connected in parallel with the inverse diode via a free-wheeling diode. An energy-consuming switching unit is connected to the storage capacitor. In or...

Beschreibung
Zusammenfassung:	A sub-module of a modular braking unit that is connected to a DC transmission network. Each sub-module has an inverse diode, and a storage capacitor connected in parallel with the inverse diode via a free-wheeling diode. An energy-consuming switching unit is connected to the storage capacitor. In order to provide a sub-module of this type such that the braking unit can function with relatively low losses in the stand-by and idle state, the sub-module is provided with an actively switchable semiconductor bypass path in parallel with the inverse diode. A braking unit has a plurality of series-connected sub-modules and we disclose a method for operating a braking unit of this type.
