Applications
Automotive
Power Ring Film Capacitors™ are used for the DC Link Capacitor used in inverters in HEV, PHEV, Fuel Cell, and EV systems. Typical voltages range from 250V – 1500Vdc and ripple currents range from 40 – 500 Arms at 10 – 100khz switching frequencies.
Military
Power Ring Film Capacitors™ handle extreme pulse power and bring higher power density, in military applications.
Alternative Energy (Solar, Wind, Grid Stabilization)
Power Ring Film Capacitors™ are the DC Link Capacitors used in inverters and in Power Conditioning Filters. They offer long-term reliability and significantly reduce costly maintenance and repairs while maximizing the energy conversion process.
Medical Equipment
Power Ring Film Capacitors™ survive extreme pulse power conditions for industry-leading shot life and allow for designs without unnecessary derating – with confidence.
Power Supply
Power Ring Film Capacitor™ offer higher density design with extremely long endurance for improved performance in your Next Generation Power Supply System.
Technology
Technical Papers
Technical papers and presentations on low Trise, low ESR/ESL, extreme pulse current survival, significant capacitance density – from various conferences.
Power Ring Technology
The ring shape (annular form factor) provides extremely low internal losses (ESR) within the film and also provides for the purest form of interconnect symmetry which can dramatically lower the inductive properties (ESL). These unique properties drive the leading edge electrical performance characteristics that the design engineer can take advantage of to develop systems with the highest level of performance and reliability.
Patented Pulse Technology
A revolutionary way of controlling the typical failure mechanism of pulse capacitors. The design makes it virtually impossible to “unzip” the way capacitors typically do when overstressed.
