Frequency Converter Voltage Low Frequency to build static Relays

摘要

The Converter is designed for the Measurement of fercuencia against to be used in the design of Low Frequency Electronic relays and aims to improve the accuracy of measurement andImprove the cost, volume and power consumption of the relay.The Converter comprises a Transformer to reduce the Voltage level, a cuadrador Wave Circuit, a low pass active filter.Working on the Band of the amplitude Attenuation characteristic of diod, a Rectifier, active Low Pass Filter,But working in the D Band Pass characteristic of amplitude and Finally an Operational Amplifier.The Converter can be used in the design of Low Frequency Electronic relays,Circuits for Frequency senalizacu00f3n impermissible and Circuits of Automatic Speed Control of Electric Motors without mechanical coupling.
