Model WE-CB-EF-1P4KV
Magnetic Field Coil Capacitor Bank Module
Bipolar Pulsed-Power Bank for Magnetic Field Coil Energization
The Magnetic Field Coil Capacitor Bank Module is a bipolar, field-proven pulsed-power supply built by Woodruff Engineering to energize magnet coil sets for magnetic reconnection research. Each module discharges a bank of eight parallel high-density metalized-polypropylene capacitors through a phase-control thyristor forward switch, crowbarred at peak current by a diode stack for reliable uni-polar-swing operation. A resistive water-dump provides primary post-shot discharge, backed by passive bleed resistors that safe the bank to below the NFPA 70E 50 V threshold within 12 hours in the event of a dump failure. The module is fully self-contained on two standard 48″ x 48″ pallets for on-site installation with a minimal connection set (facility power, coil leads, and fiber-optic control/diagnostics), and has been operating in the customer’s experimental program on this basis since delivery.

Key Features
Field-Proven Design
Built and delivered to an operating fusion research customer; in continuous service since 2016 under a 100,000-shot, 10-year design life.
Modular, Transportable Package
Fully self-contained on two standard pallets with a minimal facility connection set, enabling straightforward installation and relocation.
Redundant Safety Architecture
Primary resistive water dump, passive bleed-resistor backup, hard-wired interlocks, and Kirk-key isolation provide multiple independent paths to a safe state.
Fiber-Optic Control & Diagnostics
All triggering, timing, and diagnostic signals are transmitted via fiber optics for electrical isolation from the high-voltage bank.
