Cornell Dubilier Responds to Needs of Next-Gen EV Charger Designers

NORTHVALE, N.J. - April 14, 2023 - PRLog -- NORTHVALE, New Jersey, USA - In response to the rapidly growing demand for higher-performance DC link capacitors for EV chargers, Cornell Dubilier Electronics (CDE) has expanded its standard-product offerings with devices issued through franchise distributor New Yorker Electronics. While the inverter circuitry at the heart of EV charging stations may seem familiar to design engineers, there are operational, environmental and mechanical demands that make Level 3 EV charging stations unique. The latest designs are pushing voltages and current handling to higher levels to shorten recharge times.

Before the EV charger market started to take off, CDE was already deeply involved in the design and manufacture of DC link and pulse power capacitors for high-power applications in military and green-energy fields. This base was further enhanced by the acquisition of the custom film capacitor division of NWL in 2021.

Components available include screw terminal and snap-in aluminum electrolytics as well as polypropylene film capacitors; air or water-cooled types, with oil-impregnated or dry-epoxy construction. Constructions include multiple terminal options in metal or plastic cases. CDE's process begins with the customer providing the required specifications, including life and other application requirements. These specifications help determine if a standard or custom solution is recommended. To validate the recommendation, CDE utilizes advanced in-house thermal modeling and product testing capabilities. CDE has dedicated engineering resources to design custom DC link capacitors that meet the exact power requirements and unique mechanical packaging to fit complex applications. On the manufacturing side, the company has multiple North American manufacturing facilities.

CDE's custom-engineered DC Link capacitors are designed specifically for Level 3 EV charging applications. The high-power demands of Level 3 charging require robust DC link capacitors, having exceptional life and reliability over a broad range of operating conditions. CDE offers high capacitance values with low inductance (< 5 nH), high ripple current (100s of Amps), self-healing, and low loss dielectrics. Voltage Range: 450 Vdc to 3800 Vdc. -40 °C to +135 °C Operating Temperature, with life expectancies of 200,000 hours typical.

New Yorker Electronics is franchise distributor of Exxelia Magnetics (ex-Microspire), part of Exxelia Group, and supplies its full line of Film, Mica, Tantalum, Aluminum Electrolytics and Ceramic Capacitors as well as its EMI/RFI Filters, Magnetics, Position Sensors, Slip Rings and Rotary Joints.
