CDE introduces DC link capacitor modules for large inverter systems

10 January 2019

New Yorker Electronics will be distributing the new Cornell Dubilier Electronics (CDE) series of DC link polypropylene film capacitor modules for high-power inverter applications. The MDL series uses advanced metallized film technology for long life and high reliability in DC link applications. It offers capacitance values Source: New Yorker ElectronicsSource: New Yorker Electronicsranging from 600 µF to 4,200 µF, with applied voltages of 900 V DC to 1,300 V DC.

The MDL is based on CDE’s DC link film technology utilizing low-loss, high-grade polypropylene dielectric. Featuring current ratings up to 400 Arms, these modules are well suited for today’s high-power inverters used in commercial and utility-scale wind, solar and fuel cell systems. Other applications include UPS, switching power supplies and large motor drives.

Designed as an alternative to banks of cylindrical bus-mounted capacitors, these high-current modules have higher energy density and simplify bus connections by reducing the number of terminations. By using a single DC link capacitor in a compact rectangular package, smaller inverter topologies are possible. The use of one capacitor versus several parallel-banked capacitors typically results in enhanced system reliability with lower assembly costs. The MDL series also features long life, meeting a 5,000-hour life test at rated voltage, with a core temperature of 85° C. This translates to a life of 200,000 hours when operated at a 60° C ambient temperature at full rated voltage and ripple current.
