Essential considerations relating to partial discharge

Insulation voltage, test voltage, partial discharge and insulation strength – terms development engineers frequently have to deal with. But how are they related and which aspects and data are ultimately relevant to the developer?

Auxiliary Power Supplies for Medium and High Voltage Applications

New IGBTs and IGCTs, together with appropriate snubber and freewheeling diodes up to 5.5 kV (6.5 kV respectively), are opening up the possibility of establishing power electronics for the medium voltage level with manageable effort. Tri–level switching topologies and cascaded switching systems are the preferred architectures used here.
