PREMO has introduced its newest 4-Phase high-power common-mode chokes, 4CMCN065R0-16H, and 4CMCN065R0-32H Series, designed for EMC noise filtering in onboard chargers of up to 22Kw in electric vehicles.
These automotive-grade chokes are compact (< 5.8 cm3) and got high efficiency (>98.5%), making them the ideal solution for electric vehicle manufacturers looking to optimize their charging systems.
The 4CMCN065R0-16H and 4CMCN065R0-32H chokes feature a unique design that allows for effective filtering of high-frequency noise in power lines, while also reducing electromagnetic interference.
Their high efficiency makes them perfect for use in electric vehicles, where space and energy efficiency are critical.
The 4CMCN065R0-16H choke is capable of handling up to 16A of current, while the 4CMCN065R0-32H choke can handle up to 32A, making them both highly versatile and ideal for use in a variety of electric vehicle charging applications.
In addition to their compact size and high efficiency, these chokes also feature a range of other benefits that make them stand out from other common-mode chokes on the market.
We believe that the 4CMCN065R0-16H and 4CMCN065R0-32H chokes represent a significant step forward in the development of onboard chargers for electric vehicles. Their compact size, high efficiency, and versatile design with potential customization make them a valuable addition to any electric vehicle manufacturer’s product lineup. The designs are developed for maximum thermal coupling of core and copper with thermal interface materials like CoolMagTM.
While it is known that toroids are the optimum shapes for magnetic designs, with the shortest magnetic path and minimum core volume, so far, they were very complex and capital-intensive to automate mass production. PREMO has developed a fully automatic manufacturing process for this kind of common mode chokes, with a 100% automatic full winding process.
The current production, deployed in Vietnam plants is fully automated by using collaborative robots from PREMO RoboticsTM.
Due to this high automatization level, the high-volume demand coming from electric and hybrid vehicles is secured with top-notch quality levels.
Premo is committed to SDG’s (United Nations Sustainable Development Goals) and designs, engineers, prototypes, and test’s full reliability at its green carbon net positive Innovation Center.
This innovation will be presented at PCIM Europe 2023 at PREMO Stand Hall 6, Stand 232.
