Magnetization of a transformer core blocks AC transformer action
Rather than a Variable-voltage DC powered electromagnet, a permanent magnet solution seems quite viable.
Rather than dial more voltage for more magnetic intensity, an intense permanent magnet is instead physically moved against the ferrous core material, to magnetize the core and block transformer action.
Remember that inductance reduces through current, impeding, an electrical impedance. When the core turn turns permanently magnetized, its effective impedance is decreased. Less electrical impedance allows more current to flow through the same copper winding, without the inductive load.
Therefore: Size your conductors to handle current based purely on the resistivity of the wire, as the inductance falls away with impedance.

These experiments will lay out a series of wiring and laminate-core reconfigurations of common microwave oven transformers to afford continuously variable-amplitude AC line voltage at the expense of added windings and a DC power supply. Some re-assembly of MOT laminate cores is required.

This is not an efficient design, but got the job done in the early industrial and WWII era. This technology was largely replaced by hydraulics.

The re-purposed product could be called a poor-man's high-current variac.

As to how efficient of a design will be attempted, not very. Intended use will be for short-term

Note: This design is based on 400 Hz nautical and aeronautical power-control technology. When well engineered, a 100 to one control-power to output-power ratio was achievable back in the day.


Target bucket-list applications

Variac style use

  • DIY AC Welder current control (inline w/welding current)
  • Mini arc-furnace control
  • Electrolysis
  • Variable hi-amp DC supply
  • Variable AC —MOTiac

Available (MOTs) will be used for most tests most likely.
