Flyback Transformers
Browse our collection of flyback transformers, engineered for precision and reliability in high-voltage applications. This category includes both AC and DC models with output voltages up to 30kV, ideal for plasma generation, spark-gap systems, ignition circuits, electrostatics, and resonant energy experiments. All transformers are fully compatible with our Half-Bridge Amplifiers, allowing precise control of frequency and duty cycle for optimal performance.
While AC flybacks are technically high-voltage resonant transformers, we categorize them as flybacks since they closely resemble traditional DC flybacks in form and construction—typically differing only by the absence of an internal diode. AC flybacks can easily be converted to DC by placing a high-voltage diode in series with one of the output leads, offering flexibility across a wide range of use cases. Whether you're powering plasma tubes, generating visible arcs, or exploring high-voltage propulsion and electrostatic effects, these flybacks deliver the stability and performance trusted by advanced hobbyists, engineers, and researchers alike.
