The mechanism through which the ZVS is achieved is somewhat different for the two legs of the converter. For the left leg (S 1 and S 2), achieving ZVS is comparatively easy because, in the transition period of at left leg, the body diode of S 1 and S 2 switches can be turned on via the reflected current of the secondary inductance. Nevertheless, this is not the …
Controlled switching systems (CSSs) have become an economical solution and are commonly used to reduce switching surges for various switching applications (CIGRE TF 13.01 1995, 1996).Recent developments of transformer switching taking account of the residual flux can effectively mitigate severe inrush currents and temporary overvoltages that may lead …
Abstract: Description of a new type of operating mechanism for circuit-breakers having a rated voltage of 72.5 kV and above. It uses one moving part and is fully electronic. The energy powering the drive is buffered in a capacitor bank. The use of electronics allows for easy monitoring without the need for additional sensors.
