IGBT Snubber Capacitors

Alcon Electronics Pvt Ltd manufactures IGBT Snubber Capacitors. MP-4, MP-4A, KPF and KPF-9 series are designed for high power converters and use a low loss dielectric of polypropylene film. The capacitors with double metallised plastic film electroldes and with a metallised polypropylene as a quasi electrode with internal series construction are designated MP-4 and MP-4A. These are recommended for low and medium pulse application. Capacitors designed for extremely high pulse applications have aluminium foil as electrodes and have a metallised polypropylene quasi electrode in an internal series construction. These capacitors are designated KPF and KPF-9. The MP-4, MP-4A, KPF and the KPF-9 capacitors have self-healing properties. Another type of capacitors, which are designated KP-3C, are unique since they have extended aluminium foil electrodes with polypropylene film dielectric and are impregnated. This design is not only suitable for IGBT protection circuits and snubber networks but can also be effectively used in low and medium frequency tuning resonant circuits. Alcon range of IGBT snubber capacitors are RoHS and REACH compliant. Flame retardant characteristics are ensured by use of plastic enclosure and epoxy end fill, which conform to UL94-VO. A total 24 terminal styles and 35 case sizes are available as a standard. In addition custom designed capacitors are also available. Alcon started manufacturing aluminium electrolytic capacitors for the Indian entertainment electronics industry in 1977. Over the years the focus has shifted and the company now manufactures a large range of high CV screw terminal type aluminium electrolytic capacitors and a large variety of film capacitors. It now caters to the needs of the power electronics sector which includes not only AC drives, UPS systems and inverters but also high frequency induction heating equipment, windmill inverters, defence equipment and telecom equipment, besides a host of several special purpose industrial electronic equipment like health care, welding and pulse magnetizing to name only a few.
