    Protecting thyristors by means of fuses in electro-chemical rectifiers where more than 100 devices are used in a single unit may cause considerable service interruption when fuses open during temporary faults. This paper considers the thyristor and fuse ratings in conjunction with gate suppression techniques to achieve a protective system which allows a 17.5 MW rectifier to ``ride through'' moment...

    Power dips, interruptions, and disturbances occur frequently throughout a plant power distribution system that adversely affect plant lighting, computers, process controls, and drive systems. Critical processes that must operate continuously require an uninterruptible power supply to protect against both long-and short-term interruptions. However, most industrial processes are not critical and nee... View full abstract»

    Electrical characterization is based on a display of voltage and charge which appears as a simple parallelogram. The area is a measure of energy input per cycle and is independent of voltage waveform but very dependent on the maximum voltage. A useful model for such corona discharges employs a Zener diode to simulate the corona drop. The buffer dielectric plays a major roll in controlling the coro... View full abstract»
