Stanley A.

Meyer U-Core Bobbin – 8XA Configuration Ferrite U-Core Bobbin for VIC / Water Fuel Cell Research Join Us Product Overview This listing is for a Stanley A.

Meyer–style U-Core Bobbin designed specifically for 8XA VIC transformer configurations used in advanced water fuel cell and electrolysis research.

The bobbin is engineered to correctly fit a ferrite U-core (U126×91×20-CF13) and supports dual tube cell systems wired in series, following Meyer-inspired resonance and inductive coupling principles.

This component is intended for serious experimental builders, researchers, and developers working on high-voltage pulsed DC inductive systems.

Mechanical Specifications Core Type: Ferrite U-Core Core Size: U126 × 91 × 20 – CF13 Middle Tube Size: 30 × 21 mm Wall Thickness: 1.5 mm Configuration: 8XA Bobbin Layout Application: VIC / Inductive Step-Up Systems Electrical Use Case (Reference Design) Cell Configuration: 2 tube cells in series Drive Method: DC step-up (≈ ×200) Variac-controlled input Typical Power Chain: Variac → KBPC5006 Bridge Rectifier → 2 × 1000 µF / 400 V Vishay Capacitors (parallel) → DC (smoothed / pulsed) Operating Notes (Experimental Reference) Input Voltage: 220 VAC / 50 Hz Rectified Frequency: Half-wave unipolar after Graetz ~100 Hz Optocoupler Gate Frequency: 49–51 Hz 50% Duty Cycle Inductor Winding Reference Anode Inductor (L1 / C1): 400 turns Cathode Inductor (L2 / C2): 404 turns (typical tuning point) Fine-Tuning Guidance L2 = 400 turns (same as L1)…
