Function

CPS supplies electrical current by means of electromagnetic induction, similar to the primary-to secondary energy conversion of a transformer. However, the primary and secondary windings of a conventional transformer are placed on a common ferromagnetic core. This geometry creates a high coupling coefficient but precludes any relative movement between the two windings.





Open Core
The CPS transformer, on the other hand, stretches the primary winding into a long loop and places the secondary winding on an open-end core which surrounds the primary conductors and allows relative movement between the two. The reduced coupling of the open core geometry is offset by a higher primary frequency.



High Frequency
The CPS primary power converter takes 3-phase current available at site and converts it into a single-phase, high frequency power output. The power output is compensated to unity power factor and fed into the primary loop.



Variable Secondary Voltage
Current induced into the secondary pickup coil is rectified and converted as to existing requirements. The secondary power output can include low-voltage CD as well as three-phase and single-phase AC.
