초록
In this paper, the authors introduce a high-speed microprocessor based on automatic vacuum capacitor switch with a modified digital filter design using distributed arithmetic. The automation trends particularly the automatic vacuum capacitor switch has helped ameliorate the power factor essentials and automatically triggered to close when the line current exceeds rated value. Microprocessor relays use digital filters to extract only the fundamental and attenuate harmonics. To provide optimum speed characteristics a distributed arithmetic based filter design in the microprocessor controller which not only enhances filtering speed but additionally enables lower power consumption at the cost of area has been introduced. The result is a unified description that describes a digital filter structure down to bit level.
