CN Electronics
As the undisputed scientific and technological epicenter of South Korea, Daejeon Metropolitan City—anchored by the world-renowned Daedeok Innopolis (Daedeok Research Complex)—houses over 30 government-funded research institutes, 1,400+ high-tech venture enterprises, KAIST (Korea Advanced Institute of Science and Technology), and key defense research nodes including the Agency for Defense Development (ADD) and Hanwha Systems. The demanding technological climate of Daejeon creates a rigorous requirement for specialized power electronics, specifically DC/DC High-Voltage Output Converters capable of delivering ultra-stable, micro-ripple, and isolated voltage outputs ranging from hundreds to tens of thousands of volts.
CN Electronics stands as a premiere engineering partner and direct supplier serving Daejeon's elite research institutes, semiconductor equipment integrators, mass spectrometry developers, and aerospace defense contractors. Modern applications in Daejeon—such as electron microscopy, ion beam implantation, electrostatic chucking (ESC) in plasma etching equipment, and nuclear physics accelerators (e.g., the RAON Heavy Ion Accelerator complex)—require high-voltage power converters that transcend standard industrial off-the-shelf capabilities. Dynamic load regulation, ultra-low temperature coefficients (<25 ppm/°C), and stringent electromagnetic compliance (KC / KCC Class B) are non-negotiable baselines for high-performance operation in this market.
The global high-voltage DC/DC converter market is undergoing a paradigm shift driven by wide-bandgap (WBG) semiconductors (Silicon Carbide - SiC and Gallium Nitride - GaN), digital feedback loops, and advanced planar transformer topology. In demanding scientific applications, traditional line-frequency high-voltage supplies are rapidly being replaced by high-frequency switching converters operating at 200 kHz to over 1 MHz.
By leveraging GaN FETs with near-zero reverse recovery losses, our high-voltage converters achieve volumetric power densities up to 40W/in³, minimizing physical footprint inside dense scientific rack systems in Daejeon labs.
Utilizing zero-voltage switching (ZVS) resonant LLC topologies coupled with multi-stage Cockcroft-Walton voltage multipliers, high-voltage outputs up to 30kV are generated with minimal EMI radiation and reduced internal dielectric stress.
High-voltage bi-directional isolation barriers rated up to 15kV DC prevent high-energy transients from damaging sensitive FPGA control backplanes, essential for particle detector electronics and mass spectrometers.
Understanding local user intent and engineering requirements is crucial for providing maximum Information Gain. Our high-voltage output DC/DC power converters are custom-architected to fulfill specific sector needs across the Daejeon R&D industrial corridor:
In advanced semiconductor fabrication facilities and R&D pilot lines in Daejeon, DC/DC high-voltage converters provide continuous bias voltage (500V to 5kV) for Electrostatic Chucks (ESC) and electron beam inspection guns. Our modules guarantee precise voltage retention during dynamic vacuum plasma fluctuations.
Time-of-Flight (TOF) mass spectrometers and Quadrupole analyzer systems located in academic and national research centers demand exceptionally low peak-to-peak voltage ripple (<5 mV at 3kV output). CN Electronics delivers shielded, ultra-stable high-voltage DC/DC solutions tailored for spectrometry detectors.
Daejeon’s defense research institutes require ruggedized high-voltage power supplies for Traveling Wave Tube (TWT) amplifiers, laser rangefinders, and night-vision intensifiers. Modules feature full epoxy encapsulation (MIL-STD-810G compliant) to withstand shock, vibration, and thermal altitude extremes.
From particle detector bias lines at the Institute for Basic Science (IBS) to high-frequency medical X-ray generators used in regional medical institutions, our high-voltage converters provide rapid response programming, over-current arc protection, and precision monitoring outputs (0-5V telemetry scale).
Founded in 2006 and headquartered in Shenzhen, China, CN Electronics is a leading, technology-driven manufacturer specializing in high-precision electronics, custom circuitry, high-voltage power modules, and comprehensive OEM/ODM solutions. We bridge the gap between complex hardware blueprints and market-ready products for tech innovators worldwide, including specialized research facilities across Daejeon.
With a state-of-the-art production facility spanning over 10,000 square meters, we integrate advanced automated assembly lines with rigorous quality control protocols. Our core capabilities cover the entire product lifecycle—including rapid PCB prototyping, high-voltage transformer winding, component sourcing, high-volume SMT placement, automated potting encapsulation, and final system burn-in testing under full electrical load.
We understand that in the fast-paced hardware and scientific research sectors, agility and uncompromised reliability are paramount. That is why we have optimized our supply chain to offer seamless communication, transparent project tracking, and uncompromising quality standards (certified under ISO9001 / CE / FCC / KC protocols).
Every DC/DC High Voltage Output Converter undergoes stringent manufacturing workflows. Below is an overview of our state-of-the-art automated equipment infrastructure:
As advanced research institutes in Daejeon push the boundaries of quantum computing, high-frequency radar, and sub-nanometer semiconductor inspection, DC/DC high-voltage power supplies must evolve alongside. CN Electronics is actively implementing key technological innovations in our future product architecture:
Modern semiconductor etching and ion deposition processes involve frequent high-voltage micro-arcs. Our next-generation high-voltage DC/DC converters integrate hardware-level short-circuit detection that quenches arcs within less than 1 microsecond, protecting expensive target substrates.
Replacing legacy analog control interfaces (0-10V), our digital high-voltage platforms allow researchers in Daejeon to dynamically program output voltage, read current monitoring logs, and diagnose partial discharge events remotely over industrial network buses.
By using low-viscosity, high-thermal-conductivity silicone-epoxy hybrid resins, our converters mitigate corona discharge and atmospheric moisture ingress, maintaining stable dielectric integrity even in high humidity or non-conditioned cleanroom spaces.
Entering and operating within the South Korean technology ecosystem requires strict adherence to localized and international regulatory standards. CN Electronics ensures seamless integration for Daejeon clients through complete documentation and testing support:
Our high-voltage DC/DC converters are engineered to meet South Korean KC Certification (Electrical Safety & KCC EMC Standards), alongside global standards including IEC/EN 62368-1 for IT/Industrial gear, IEC 60601-1 (2x MOPP) for medical diagnostic platforms, and RoHS 3 / REACH compliance.
We provide dedicated FAE (Field Application Engineering) support for research teams in Daedeok Innopolis. Whether you require custom input voltages (e.g., 24VDC, 48VDC, 300VDC bus) or specialized output voltage profiles (up to 20kV with custom pinouts), our engineering team responds with prototype samples in as short as 14 business days.
In industrial and laboratory electronics, high voltage output DC/DC converters typically convert a low DC bus voltage (such as 5V, 12V, 24V, or 48V DC) into output voltages starting from 100V DC up to tens of kilovolts (kV DC). These modules feature specialized insulation transformers, potting encapsulation, and strict isolation layout to prevent electrical breakdown.
We utilize multi-stage Pi-filtering on both input and high-voltage output lines, continuous Faraday shielding around high-frequency transformers, and zero-voltage switching (ZVS) topologies. This results in output ripple figures below 10 mV peak-to-peak (or <10 ppm), essential for mass spectrometers and electron beam detectors.
