Research and market on energy efficient batteries, power supplies and power converters is growing rapidly worldwide. In certain layouts of switch mode power converting devices medium voltage signals have to be measured – but riding on a huge common mode voltage – easily reaching hundreds, if not thousands of Volts with increasing switching speeds. Therefore special care has to be taken by the engineers to make the measurements reliably and safely for themselves and their environment. This presentation will discuss methods for safe measurements and introduce a new technology for perfectly isolated and therefore safe meaurements on systems with high common voltages found i.e. on switching stages of switch mode power supplies.
