Christmas Light
’Twas the night before Christmas when all through the house
No electrons were flowing through even my mouse.
All devices were plugged by the chimney with care
With the hope that St. Nikola Tesla would share.

The paper gives a description of the poloidal field power supplies and the control system of the HT-7U superconducting tokamak required to energize the magnetic field coils for plasma excitation and confinement. An original configuration of alternating-current/direct-current (dc) converter, thyristor dc circuit breaker, and power supply control system are introduced in detail.
