PPM Power supplies a wide portfolio of high voltage capacitors from specialist manufacturers including Advanced Conversion, API and CKE/Dean Technology.  The main technologies available are:

DC Link Capacitors including customised and standard solutions with extremely low ESR and ESL, plus high performance DC link test kits with cooling.

SiC Test Kits with integrated cold plates, busbars and DC link capacitors, for rapid and high-performance prototype evaluation of 3 or 4 phase inverters and similar topologies.

Snubber Capacitors for thyristor, IGCT, GTO and IGBT devices, with custom capabilities.

Ceramic Capacitors for applications requiring low dissipation factor, small voltage coefficients and stable temperature characteristics.

Energy Storage and Pulse Capacitors offering extreme energy storage/pulse power density in small packages and custom designs.

Mica Capacitors for applications requiring high stability, tight tolerance and low losses.

To discuss your specific requirements, please call us on +44 (0)1793 784389 and talk to a member of our technical sales team.
