What appliances have flyback transformers?

1. CRT Televisions and Monitors: Cathode ray tube (CRT) televisions and monitors use flyback transformers to generate the high voltage needed to accelerate electrons toward the screen, which creates the images.
2. Switch-mode Power Supplies: Flyback transformers are widely used in switch-mode power supplies (SMPS) found in various electronic devices, including computers, TVs, LED lighting, and mobile phone chargers. They are used for voltage conversion and energy storage.
3. Microwave Ovens: Microwave ovens use flyback transformers to step up the voltage from the low-voltage power supply to generate the high voltage needed to power the magnetron, which produces the microwave radiation for cooking.
4. Compact Fluorescent Lamps (CFLs): Some compact fluorescent lamps use flyback transformers to step up the voltage from the low-voltage supply to generate the high voltage needed to excite the gas in the fluorescent tube.
5. Induction Heating Equipment: Flyback transformers are used in induction heating equipment to step up the voltage from the low-voltage power supply to generate the high-frequency high voltage needed for induction heating.
6. Electronic Ballasts: Some fluorescent lamp ballasts use flyback transformers to generate the high voltage needed to start and regulate the operation of the fluorescent lamp.
7. HVAC Systems: Heating, ventilation, and air conditioning (HVAC) systems may use flyback transformers in control circuits, such as in electronic thermostats or control panels.
8. X-ray Machines: Some medical and industrial X-ray machines use flyback transformers to generate the high voltage needed to produce X-rays.

These are just a few examples of appliances and devices that may incorporate flyback transformers. Flyback transformers are versatile components that find applications in various electronic devices and systems where high-voltage isolation, voltage conversion, or energy storage is required.
