Title:
電圧積分器及び当該積分器を設けられた変圧器
Document Type and Number:
Japanese Patent JP2008528997
Kind Code:
A
Abstract:
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.
