This high frequency, high voltage transformer is designed for many specialized applications such as solid state Tesla coils, plasma displays, Jacob's Ladders, drivers for DC multipliers or general purpose high voltage sources. High quality silicon rubber potting is used for the secondary coil. Output is a flexible silicon insulated lead.

40kV pk-pk at 30ma, current limited 15kHz-60kHz operating frequency, with 3" size large UU69 ferrite core and flexible silicon output lead. 4000 turns #37 on secondary with silicon output lead. Customer makes their own easy-to-wind primary which is usually 30 to 50 turns of Litz wire, depending on voltage and operating frequency required. Core is air gapped and can easily be changed if needed for controlling secondary current. For end point grounded circuits. Excellent for powering plasma loads, displays, jacob’s ladders or other negative resistance loads. Short circuit proof. (We can manufacture these, and variations, in large volume for the trade; contact us by phone 603-673-4730 or email.)

Here is an example of a PVM400 schematic.

Primary Coils

The FLYPVM includes the secondary coil and ferrite u-cores, but does not include a primary coil as many prefer to wind their own. However we do offer the primary coil if needed, and you can adjust the number of turns to your requirements:

FLYPVM primary coil, 50 turns of #20 Litz wire

FLYPVM primary coil, 80 turns of #20 Litz wire
