Average current-mode control (CMC) requires that the total waveform of the current be reconstructed for the control loop. This article presents the steps required to select the transformer and how to ...

Current sense transformers (CST) are used for controlling and protecting circuits as well as detecting loads in power supplies. Epcos has developed two new CST series that are particularly suited for ...

A range of manufacturing and production processes rely on current-operated relays to provide a continuously adjustable trip-current setting. They are able to protect mechanical apparatus from jam-up ...
