About Us

Cougar Electronics Corp. was founded in 1968 and bought the General Instrument Selenium Rectifier Division. The company has manufactured Selenium Rectifiers since that time originally in Brooklyn and now in New Haven.

Who we are?


n 1996 my partner and I bought Cougar and in 1998 moved to New Haven. In the beginning we built up our business by diversifying into other manufacturing and distribution of complementary products in the Power and High Voltage areas.

Over the last 18 years we have had to re-invent ourselves many times over due to the ever changing nature of the electronics business. In the beginning a large part of our business was with the Elevator Industry and this is still a part of what we do, but today we service many industrial areas including Transportation, Rail & Bus; Welding Equipment; Oil & Pipeline Protection Equipment; Automation Equipment; Medical Equipment; plus many other high power industrial applications.

In the past few years our biggest growth area has been the building and refurbishing of Power Supplies for the Plating industry. We have built a solid customer base in the Northeast supplying Plating supplies that range from 25amps to 15000amps. The key to this has been our service, quality and delivery which we have accomplished by our well trained and dedicated staff.

About Us

There has been a notable increase in the developpment of Silicon Carbide semiconductor materials (SiC) in the past few years. It seems we are now close to a massive use of those new solutions, made possible by the considerable number of peoples working on the subject and price drop down. The adoption of SiC solutions are mainly driven by two factors : the miniaturization and the efficiency. Silicon Carbide based devices are a very promising answer to the market pressure on power converters compactness and efficiency. The lower maximum junction temperature, allow higher density of power on the semiconductors, wich leads to decrease the size of the cooling components. Nevertheless, this positive effect is also making the thermal management challenge harder. Water cooled and heat pipes solutions are now commonly considered by power electronics engineers see cougar electronics solutions for thermal management [caption id="attachment_2308" align="aligncenter" width="300"]Silicon Carbide Silicon Carbide Losses[/caption] SiC are also well known for their capacity to work at higher frequency than classical silicon based MOSFETs and IGBTs. The magnetics components size like inductors, and transformers is mainly linked to the frequency. In this way, increasing the frequency of the device drastically allow to reduce the size and thus the weight of the magnetics components. SiC technology has been massively adopted by early adopter applications like Solar Inverter and UPS. The adoption of this new technology is slower in the high power industry like motor drives, tractions and electrical grid converters due to the reluctance in the use of new material. The market of high power Silicon Carbide semiconductors is mainly holded by niche players, that were pioneers in their field. Most of the big semiconductor manufacturers are releasing or close to release new range of devices that will trigger the signal of a massive adoption.
