A circuit simplification for AC power supply surge protection devices
ثبت نشده
چکیده
As far as the design of SPDs is concerned, the need exists for simplifying its circuit structure in fulfilment of the prerequisite condition of protective reliability. The circuit simplification for SPDs is of benefit to lower the cost of manufacture and reduce the size of chassis. Considering that the traditional SPD that has been extensively used on single-phase AC power supply lines requires to be assembled by more protective components, a simplified circuit is proposed in this paper for an improvement on SPD design.

A NOVEL TRANSDUCER FOR MONITORING SURGE CURRENTS IN AC MAINS: Expectations and Reality
The proliferation of surge-protective devices and switch-mode power supplies has radically changed the surge environment in the low-voltage AC mains. Monitoring surge voltages has lost significance and can be misleading. Instead, surge currents should be monitored. The paper describes the performance of a silicon-based surge-protective device acting as a "magnet" for impinging surges in the pre...

A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...
