High Voltage DC Power Supply [DC Power Supply for Accelerators] with Production Examples!

High Voltage DC Power Supply [DC Power Supply for Accelerators] with Production Examples!

It is possible to design and manufacture high-voltage DC power supplies for special purposes used in large-capacity electrostatic accelerators and similar applications.

We introduce the high-voltage direct current power supplies handled by Takenaka Seisakusho Co., Ltd. When a large-capacity high-voltage direct current power supply using SiC-MOSFET resonant technology is configured as a static accelerator, the acceleration voltage can range from several hundred kV to several MV (with acceleration energy around several hundred keV to several MeV), and it becomes possible to commercialize large-capacity electrostatic accelerators with acceleration currents ranging from several tens of mA to several hundred mA. We specialize in contract development and manufacturing of high-voltage direct current power supplies for special applications. *For more details, please refer to the PDF materials or feel free to contact us.
