A Flyback transformer is a high-voltage, high-frequency transformer used in plasma balls and with cathode-ray tubes (CRTs). It provides the high (often several kV) anode DC voltage required for operation of CRTs. Variations in anode voltage supplied by the flyback can result in distortions in the image displayed by the CRT. CRT flybacks may contain multiple secondary windings to provide several other, lower voltages. Its output is often pulsed because it is often used with a voltage multiplier, which may be integrated with the flyback.
