Guangdong Fenvix Technology presents field-proven high-voltage solutions engineered with sub-millisecond charging linearity, zero-overshoot quench control, and extreme EMI shielding compliant with global research standards.
0–100kV Charger
0–100kV Capacitor Charging & Discharging Power Supply
Modern pulse-power engineering places unprecedented stresses on charging topologies. Conventional DC power supplies operating under constant-voltage (CV) or brute-force series-resistor schemes experience massive thermal dissipation during the initial phase when an uncharged capacitor presents an effective electrical short circuit (Vcap = 0). When exporting capacitor charging high voltage power supplies to expanding industrial and research hubs like the Nampo industrial market, Guangdong Fenvix Technology deploys advanced LC/LLC Series-Parallel Resonant Inverters operating under true Constant-Current (CC) and Constant-Power charging regimes.
This closed-loop topology delivers linear voltage ramps (dV/dt = Ich / C), preventing initial current spikes, eliminating transformer saturation, and securing operational efficiencies exceeding 90%. As the target voltage approaches setpoint tolerances, our proprietary DSP controller seamlessly shifts the gating duty cycle from maximum charging cadence to sub-resonant trickle regulation, suppressing overshoot to less than 0.1% of maximum ratings across repetitions ranging from single-shot detonations to multi-kilohertz pulsed laser systems.
Zero-Voltage Switching (ZVS)
Phase-shifted resonant bridge topologies ensure IGBTs switch under zero voltage conditions, drastically diminishing thermal de-rating and eliminating EMI interference with sensitive laboratory instruments.
Arc Arrest & Flashover Protection
Equipped with sub-microsecond crowbar clamp circuits and transient energy dump arrays, safely absorbing instantaneous short circuits when capacitive banks flashover or break down.
Multi-Segment Voltage Profiling
Programmable ramp rates via isolated Modbus-RTU, CANopen, or fiber-optic interfaces, enabling custom energy accumulation curves to preserve the life cycle of high-energy discharge capacitors.
Localized Engineering Deployment in the Nampo Industrial Corridor
The port infrastructure, heavy industrial facilities, and engineering research hubs surrounding Nampo demand resilient power equipment capable of withstanding stringent operational conditions. With coastal atmospheric conditions generating salt fog corrosion, coupled with frequent local power grid harmonics from heavy shipbuilding machinery and mechanical workshops, equipment reliability cannot depend on light commercial assemblies.
Heavy Marine Metallurgy & Ship Component Cladding
Applied directly in pulsed-plasma nitriding, electron-beam welding acceleration, and electro-hydraulic metal forming for shipbuilding panels and offshore platform mooring gears across Nampo dockyards.
Industrial Water Filtration & Chemical Electrolysis
Powering pulse-discharge water sterilization, advanced electrolytic oxidation for harbor effluents, and polarity-reversing descaling arrays operating in harsh coastal chemical facilities.
High-Energy Physics & Materials Testing
Providing rock-solid charging cadence for Marx bank generators, flash X-ray non-destructive testing (NDT) of structural castings, and pulse-driven laser optics in regional polytechnic institutes.

Procuring specialized high-voltage capacitor charging infrastructure requires exact configuration matching. Here are direct answers to common questions raised by electrical plant managers and research procurement teams:
How do I size the charging rate (Joules/sec) for our capacitor bank?
The peak charging rate is governed by J/sec = 0.5 × C × (Vmax2) / tcharge. For continuous repetitive pulse systems, add a 15–20% thermal margin to account for dielectric loss and voltage holding periods. When you provide your capacitance (μF), peak charging voltage (kV), and target repetition rate (Hz or time in milliseconds), Fenvix application engineers size both the peak kVA rating and resonant tank inductance.
Can Fenvix high-voltage systems handle repetitive short-circuits during pulse discharge?
Yes. Our high-voltage capacitor charging units integrate instantaneous inhibit lines linked to your pulse discharge switch (e.g., thyratron, spark gap, or solid-state IGBT switch). The power supply gating is suppressed during the discharge window, preventing current pass-through. In addition, internal multi-stage inductors and reverse-energy blocking diodes absorb energy reflections resulting from impedance mismatch.
What electrical inputs and cooling arrangements are accommodated for export?
We build to world electrical standards: 3-phase 380V, 400V, 415V, or 480V at 50Hz or 60Hz. Cooling choices include forced-air cooling for cleanroom and rack installations up to 30kW, or closed-loop deionized liquid cooling for heavy-duty 75kW–300kW continuous installations in dusty or corrosive atmospheres.
What control protocols are supported for automated PLC test lines?
All units feature standard galvanically isolated RS485 (Modbus-RTU) ports and analog 0–10V / 4–20mA monitoring interfaces. For elevated electrical noise environments (pulsed lasers and Marx banks), we offer optical fiber I/O conversion to fully decouple high-voltage ground bounce from your host PLC or PC controller.
What international trade terms and payment modalities are supported for delivery to Nampo?
Guangdong Fenvix provides complete export logistics support across standard international terms including FOB Guangzhou/Shenzhen, CIF, CFR, FCA, CPT, and DDP seaport/airport options. Payments can be structured through wire T/T, irrevocable confirmed Letters of Credit (L/C at sight), and multiple currency settlements (USD, EUR, CNY, etc.).
