What is the Flyback transformer?

Flyback Transformer is a main part of a flying converter that generates high voltages usually on cathode rays such as TV sets and oscilloscopes. It relies on the rapid falling edge of the horizontal scanning signal. This transformer is able to generate tens of thousands of direct current volts (VDC) due to the relatively high audio frequency of the horizontal phase of grooving the beam. Compared to other line output transformers, Flyback transformer has the highest high -voltage insulation requirements. The internal structure of the flrying transformer must be without moisture and must have the correct pitch between the parts of the layer winding with increased voltage differences. With high voltage semiconductor rectifiers, they are used with a Flyback transformer to generate high voltust. Electric transformers generate a higher or lower voltage or the same as its input. The transformer can increase, withdraw or just insulate the input from the output voltage. Input voltage in the transformerU is converted into a magnetic field, while the output voltage is generated regularly by a magnetic field collapse.

Flyback transformer impedance is a combination of resistance and frequency sensitive reactance due to capacitors and inductors. Resistance to direct current (DC) can be measured using a conventional Ohmmer, which works with a low -voltage DC power supply such as 1.5 V) batteries. Impedance depends on frequency; For example, the speaker sound impedance applies to an audio range from about 100 cycles per second (CPS) to about 20,000 Hertz (Hz). For performance, audio and other applications, the output transformer of the insulation line and the comparison of impedance is used. In the sound, the output transformer may have a high primary winding impedance such as 3,000 ohms, while secondary impedance could correspond to the speaker system impedance usually in the range of 2 to 8 ohms.

Vacuum tube circuitsThey use output transformers of the type of vacuum tube with a primary winding impedance of something like 10,000 ohms. This results in the use of so many speeds of fine magnetic wire in building transformers for pipe types. A higher voltage used for tube type circuits cause the design of the flryback transformer to rely heavily on good insulation material between the winding of the layers. When storing and using tapes and insulators boards, high humidity used to separate the winding layers avoids. These materials are also able to maintain insulation even at elevated temperatures that occur during normal operation.
