SELF PROTECTED SURGELESS CAPACITOR FOR POWER-FACTOR CORRECTION

Abstract Self protected surge-less capacitor for power factor correction comprising the power capacitors which are switched through the electronic solid-state switches like Thyristors, Solid state relay, said switching devices are mounted on the heat sink, the controlling of said switches is done through electronic control circuit, and the said control circuit incorporates Integrated circuits and semiconductor devices, there are three arms for three phases R, Y and B, each said arm has separate control for switching said switching devices, current sensors are inserted in each said arm to sense current and feedback to the said control circuit, the said control circuit detects abnormal conditions on the basis of the said feedback signal and disconnect the control command of electronic switches to make them OFF or to isolate the Capacitor from line, the complete assembly is enclosed in a conventional enclosure and the power supply required to control the operations of the said self protected surge-less capacitor which is on the said control circuit itself.
