WE-OR-35
3kV / 3kA High-Voltage Pulsed Power Supply
Capacitor-Bank Discharge PSU for Pulsed Magnet & High-Energy Physics
The Woodruff Engineering High-Voltage Pulsed Power Supply Model WE-OR-35 delivers 0–3 kV output at up to 3 kA peak current through a rack-mounted capacitor-bank discharge architecture, utilizing an internal 600–700 μF high-voltage capacitor array optimized for rapid energy delivery into pulsed electromagnet, plasma discharge, or transient test loads. The system features fiber optic trigger input for electrical isolation and immunity to electromagnetic interference, responding to external trigger commands in under 1 millisecond to initiate capacitor discharge through controlled thyristor or IGBT switching networks. This fast-trigger capability combined with the substantial stored energy (up to 3.15 kilojoules at 3 kV) makes the WE-OR-35 ideally suited for applications requiring repeatable high-current pulses with precise timing control, including fusion diagnostics, electromagnetic forming, capacitor discharge welding, and pulsed magnetic field research where microsecond-level synchronization between multiple power channels is critical.

Pulse Lifetime
The WE-OR-35 is designed explicitly for multi-unit synchronized deployment. This system enables coordinated operation of up to six independent power supplies discharging within ±0.050 milliseconds of each other – critical for applications such as multi-coil pulsed magnet arrays, phased plasma heating systems, or distributed electromagnetic launchers where field uniformity or precise energy sequencing depends on sub-millisecond timing accuracy across parallel channels.

Key Features
Fiber Optic Trigger for EMI Immunity
Electrical isolation via fiber optic trigger input eliminates ground loops and provides complete immunity to electromagnetic interference during pulsed discharge events.
Multi-Unit Synchronization (±50 μs)
Designed for coordinated operation of up to six independent WE-OR-35 units discharging within ±50 microseconds of each other from a common trigger source, enabling applications where precise energy delivery timing across multiple channels is critical.
Ethernet UDP Control (SOUP Protocol)
SOUP provides lightweight, low-latency network control for voltage setpoint (10V increments), arming/disarming, and real-time status monitoring over standard Ethernet infrastructure.
Three-Tier Safety Architecture
Active automatic dump circuits, passive slow bleed resistor networks, and fail-safe isolated floating high-voltage rail architecture prevents dangerous fault conditions, maintaining operator safety.
Compact Rack-Mounted Deployment
Standard 19-inch rack enclosure (≤22″ H × 19″ W × 34″ D, <150 lb) with IP30 ingress protection enables installation of three complete WE-OR-35 units per standard 42U equipment rack mounted on heavy-duty castered frames.
High-Energy-Density Capacitor Bank
Low equivalent series resistance (<10 mΩ) and inductance (<500 nH) enable fast rise times (<10 μs into resistive loads) and high peak power delivery (~4.5 MW instantaneous), while self-healing film technology ensures reliable long-term operation.
