50 kV Capacitor Chargers for Pulsed Power and PFN Systems
USE CASE
Large research facilities and pulsed power systems require capacitor chargers that deliver high voltage, repeatable energy and reliable operation over many years. Technix HV designs capacitor charging power supplies for PFN and pulsed systems, including 50 kV chargers used in demanding synchrotron and neutron/muon source applications.
Application context
Pulse Forming Networks (PFN) require controlled charging before energy is released into pulsed loads. In research facilities, the charging system must operate repeatedly, safely and predictably, often under strict timing, control and interlock requirements. Reliability is critical because downtime can affect major scientific programs.
CUSTOMER CHALLENGE
• Charge PFN systems at 50 kV with stable and repeatable performance.
• Support continuous repetition rates above 10 Hz.
• Deliver high charging power in a compact format.
• Maintain robustness and long-term reliability in a major research facility.
• Provide custom interfaces compatible with existing control and safety systems.
• Enable future expansion while preserving compatibility with installed chargers.
TECHNIX HV SOLUTION
Technix developed 50 kV - 10 kJ capacitor chargers delivering 10 kJ/s charging power for PFN applications. The chargers were designed for high-voltage operation, continuous operation above 10 Hz and integration into the facility’s existing control and safety architecture. More than ten years after installation, the systems continue to operate reliably, leading to additional units being selected for expansion.
Key benefits
• Repeatable PFN charging for pulsed experiments.
• Long-term reliability demonstrated over more than a decade of operation.
• Compatibility with existing control and safety systems.
• Compact charging architecture for high-energy applications.
• Expansion capability with matching additional chargers.
Where PFN chargers are used
PFN capacitor chargers are used in pulsed power installations, accelerator systems, synchrotrons, neutron and muon sources, pulsed magnets, modulators and other research or industrial systems requiring controlled high-energy pulses.
Key capacitor charger requirements
Important design factors include voltage rating, energy per pulse, repetition rate, average charging power, voltage regulation, pulse-to-pulse repeatability, discharge inhibit functions, safety interlocks, connector design, remote control and serviceability.
What is a PFN capacitor charger?
A PFN capacitor charger charges a Pulse Forming Network to a defined high-voltage level before the stored energy is released as a controlled pulse.
Can Technix supply high-repetition-rate chargers?
Yes. Technix has developed capacitor chargers for applications requiring continuous operation above 10 Hz.
Which product range is relevant?
Technix CCR capacitor charging power supplies are the relevant range for PFN and pulsed power applications.
