Transformers - HV Flybacks, HF, Parts, etc.


https://cdn1.bigcommerce.com/server800/64f33/content/Graphics/single-page-view.png

This page shows our high-frequency ferrite Transformers.

Unlike the conventional iron core, these deliver many times the power in a smaller lighter package. They require a high frequency circuit to operate and cannot be directly powered by direct 115 vac. (For 60Hz iron core transformers powered by 115VAC, see our page here.)

We supply ice cube sized units to the much larger flyback types. They have proven their reliability as many are still in service for over 20 years! These efficient units were designed in our USA laboratories and manufactured in our HK facility. They are used for general high voltage circuits, weapons, health, neon signs and many other high voltage applications. Purchase of three or more units will include a working circuit diagram with all instructions. Volume discounts are readily available.

Our FLYPVM-series transformers used in conventional high-voltage high-frequency power supplies will power such devices as our JACK30 jacob ladder, AUDIOARC speaker, PVM400 plasma display power supply, HVPSD400KV DC HV, and more. They can be used in a resonant mode for tuning out the capacitance in plasma cells and containers as used in our PVM500, and higher power PVM2000 resonant mode drivers.

  • Secondary coils are rated at 40,000 V peak to peak and are end point grounded. Coils are potted in a hard epoxy molded shell.

  • They are easily disassembled for changing air gaps and winding different primaries. Most applications will require a primary of 30 to 60 turns depending on the drive circuits and frequencies you intend to use.

  • When purchased they are ready to use with 2 mil air gaps and come taped together, only requiring the primary winding.

  • The standard transformer comes with core size of 2.7 x 3 x 0.625". An optional larger core size is available of 3.25 x 3.25 x .0625" allowing the builder to obtain more power from his circuit.

UNIVERSAL HIGH VOLTAGE TRANSFORMER MAY BE USED IN SEVERAL CIRCUIT CONFIGURATIONS Capable of providing 30kV pk to pk, 15kHz-70kHz operating frequency.

High output intended for CO2 lasers or as a driver for Cockroft Walton voltage multipliers up to 300KV at 2ma. Circuitry may use pre-wound primary of 40 turns and secondary that are on same leg for low leakage application. These leads can be insulated to preserve for different circuit.  You may hand wind primary on opposite leg for high leakage reactance for negative resistance loads. Core is a “beefy” 2.7 x 3 x 0.675" U core set. Secondary is wound with 1000 turns of #34 wire. For endpoint grounded circuits. (We can manufacture these, and variations, in large volume for the trade; contact us by email.)
