Abstract

PURPOSE: To increase frequency conversion precision by a method wherein a fundamental wave filter is connected to the output side of a ferroresonance type transformer in which the input voltage whose frequency is to be measured is impressed on its input side, and the relationship between frequency and voltage is made so that it can be expressed by a linear equation.
CONSTITUTION: AC voltage, whose frequency is to be measured, is applied to the input terminal a of ferroresonance type transformer circuit 1, and this AC voltage is impressed on ferroresonance type transformer T1. Fundamental wave filter 2 is connected to the output winding of this transformer T1, and thereby the spike which is to become noise produced in the output of transformer T1 is removed, and only the fundamental wave is taken out. The fundamental wave taken out in this way is rectified by full wave rectifying circuit 3, and thereby a voltage proportional to the frequency of the input is produced. The relationship between this voltage V and frequency f is expressed by the linear equation f=kv/2πBmax, where k is a constant determined by the circuit connection, and Bmax is the maximum saturation magnetic flux density of transformer T1.
