What is the flyback inductor?

Flyback Inductor is a transformer designed to generate a high -frequency, high -frequency signal signal. Flyback inductors, also known as FLYBACK (FBT) or LOPT line transformers, give specific requirements for the cathode beam tube signal (CRT) on TV and computer monitors. Flyback inductor usually also has secondary outputs with lower voltages that give other parts of the monitor circuit. Flyback inductors differ from conventional transformers in that they are able to store energy in their windings for a moment when the power supply is reduced. This is achieved by placing the primary and secondary winding on the ferrite core with a carefully calculated air gap between two, which serves to increase unwillingness or the ability to store energy.

CRT on TV and monitors used in computers, ATMs, game machines and sales stationsComplete the extremely high voltage at high frequencies, usually 20,000 to 30,000 volts and 15 to 150 kilohertz (KHz). A specific signal profile known as the saw course is also required to control the horizontal deflection or movement of the electron beam of the pipes. Both requirements are met by Flyback inductor. This component is essentially a specialized transformer consisting of the primary and secondary winding located on the ferrite core with an air gap between them. The main difference between the design and the operation of the flocking inductor and the conventional transformer is the carefully calculated air gap between the two winding and the resulting increase in the inductor's unwillingness.

Reluity is a term that describes the ability of the inductor to store the charge caused in its secondary winding for a moment after the energy is reduced. This characteristic together with the relationship between wire thickness and the number of turns on primary and secondary winding allow the inductor of flying high -voltage and high -frequency signal retention signalCRT. The SELLOOTH signal formula is achieved using the monitor circuits that switch the Flyback inductor in a continuous, controlled manner. This switching is usually achieved by transistors that allow the delivery to increase to the top with a steep milestone, providing the inductor output signal of its characteristic pilot profile.

Secondary winding of many Flyback inductor models includes taps or secondary outputs used to supply lower voltages to other parts of CRT circuit. When disconnecting the Flyback inductor from CRT, care should always be taken, even if the energy to the monitor was disconnected. The residual charge stored in the inductor can cause ugly impact and electric burns if the CRT line touches before complete discharge.
