VOLTAGE INTEGRATOR AND TRANSFORMER PROVIDED WITH SUCH AN INTEGRATOR

摘要

A voltage integrator, comprising a resistor (4) and a capacitor (5) connected in series between an input voltage (V) and ground, wherein the resistance (R) of said resistor and the capacitance (C) of said capacitor are adapted such that a voltage (Vc) across said capacitor approximates the integral of said input voltage (V). Means are provided for preventing said capacitor voltage (Vc) from falling below a lower limit, preferably zero, thereby ensuring automatic initialization of the integrator after each integration cycle.
