Abstract

PURPOSE: To compensate the ineffective power, by connecting capacitor to the secondary side of the induction voltage regulator IVR and changing the secondary voltage of IVR.
CONSTITUTION: The voltage signal obtained at the voltage transformer 10, load current signal obtained at the current transformer 13 provided at the load circuit, and current signal of the induction voltage regulator IVR7 are inputted to the control unit 12. The control unit 12 obtains the difference between the delayed and advanced ineffective power, and if this difference is positive, the secondary voltage of IVR7 is increased, and if negative, decreased. To compensate the ineffective power, IVR7 and leading capacitor 8 are used, allowing to avoid the production of higher harmonics and to constitute the circuit with no contacts.
