Capacitor Charging Power Supplies

Stangenes Industries specializes in producing high-voltage capacitor charging power supplies for rapid, precise energy delivery in pulsed power applications. These systems excel in environments that demand quick charge and discharge cycles, including linear accelerators, lasers, medical devices, and high-energy research equipment.

Built for consistent performance and precise control, our capacitor charging power supplies are available in multiple configurations, from modular units to fully integrated turnkey systems. Each is engineered for long service life, fast repetition rates, and efficient power conversion customized to meet your exact requirements.

Our Capacitor Charging Technology

Our capacitor charging power supplies use advanced power conversion designs to meet high-voltage and high-frequency demands. At the core of these systems are high-speed IGBT switches configured in quasi-resonant, zero-current-switching topologies, which reduce switching losses and overall system weight.

Many models operate without oil or dielectric fluids, instead using air-insulated or solid-state designs that simplify maintenance and improve safety. Our Optimized Charging Cycle (OCC) technology manages peak power draw from the AC line, making these systems well-suited for charging large capacitor banks without exceeding facility power limits.

With rapid recharge capabilities and precise energy delivery for every pulse, our systems support demanding pulsed power environments while maintaining energy efficiency.

General Information

Stangenes Industries has developed several advanced capacitor charging technologies. Our state-of-the-art power conversion units utilize IGBT switches operating at high frequency in a quasi-resonant design utilizing zero voltage switching topology. These units often contain no oil or other dielectric fluids, so these units are significantly lighter and more reliable than comparable units. The advanced Optimized Charging Cycle (OCC) that we have developed reduces the peak power consumption from the line. This feature enables charging of large capacitor banks without exceeding the allowed average power.

Specification Ranges

Stangenes has produced power supplies utilizing these technologies at many different power levels and output voltage configurations.

10kW to 2MW
Single digit kilovolts to hundreds of kilovolts
Power Supplies for high repetition modulators for magnetrons and klystron, as well as many industrial applications

We are constantly expanding our product line and many new configurations are in the pipeline today including designs for hundreds of kilovolts and hundreds of kilowatts.

SCR Controlled DC Power Supplies

Stangenes Industries produces SCR controlled DC power supplies in standardized configurations or to customer specifications. These supplies operate on conventional 50-400 Hz power sources and supply output voltages that range from a few kilovolts to over 300kV with power rating from ten kilowatts up to a few megawatts average. The DC power supplies can be supplied as components of a system or a complete “turnkey” system.
