The method involves charging a circuit branch with an operating current. The current is limited under application of a test resistance than that of a circuit resistance of the circuit branch. Superimposition of the operating current at a time period along ...

A control method, device and a power converter control device for efficiently controlling energy by utilizing a step-up/step-down chopper (DC-to-DC converter) to control the amount of energy stored in an electrical power storage device installed in direct ...

Rupture on continuous current overhead conductors (FC1p1, FC1n1) is detected by installing an audio frequency generator (EMv1f1) at the sending end and two corresponding receivers (REv1p1, REv1n1) at the receiving end. The generator and receivers are conne...
