The lower conduction power losses and the positive temperature coefficient that favours parallel connections, make Silicon Carbide (SiC) metal oxide semiconductor field-effect transistors (MOSFETs) to be an excellent replacement of existing Silicon insulated gate bipolar transistors (IGBTs) technology. These characteristics combined with high switching frequency operation, enables the design...
The design and development of a High Voltage distribution system (HVDS), Smart Switch (SS) which acts as a Demultiplexer, to distribute one high voltage(HV) input into six High Voltage output channels. It provides, and independently voltage and current monitors. Each output channel of the SS has independent, ON-OFF, current and HV monitoring, as well as filtration, isolation, and a...
The high voltage (HV) system of TileCal, the ATLAS central hadron calorimeter, is being upgraded for the HL-LHC, in the so called Phase II Upgrade. In the new configuration for the upgrade, the HV regulation boards are not located inside the detector anymore, they are deployed far from the radiation in a room where there is permanent access for maintenance. This option requires a large number...
