To ensure safe re-energizing of an overhead distribution feeder after it is de-energized for an extended period, a novel fault detection technique by controlling a thyristor-based device is proposed in a companion paper. The device connected in parallel with a breaker or recloser can inject electrical pulses with adjustable strength for the downstream fault detection in a de-energized system. The...
A 5th-order Chebyshev active RC complex filter for wireless sensor networks with automatic frequency tuning is presented in this paper. This filter is synthesized from 5th-order low-pass LC prototype, and designed using leapfrog structure. An automatic frequency tuning is used to prevent the deviation of the RC constant of the filter. This filter is fabricated in TSMC 0.18μm CMOS process. The measurement...
Parametric analysis of Thomson-coil actuator has been done by utilizing the adaptive equivalent circuit method. Through the analysis of circuit parameters and plate dimensions, an optimal design of the actuator is obtained.
