PREMO has released its latest four-phase high-power common-mode chokes created for EMC noise filtering in onboard chargers of up to 22Kw in EVs, the new 4CMCN065R0-16H and 4CMCN065R0-32H Series. These automotive-grade chokes are compact in size (< 5.8cm3) and have high efficiency (>98.5%), making them the ideal solution for electric vehicle manufacturers looking to optimise their charging systems.
The 4CMCN065R0-16H and 4CMCN065R0-32H chokes feature a unique design that effectively filters high-frequency noise in power lines while reducing electromagnetic interference. Their high efficiency makes them perfect for EVs, where space and energy efficiency are critical. The 4CMCN065R0-16H choke can handle up to 16A of current, while the 4CMCN065R0-32H choke can handle up to 32A, making them 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. These include:
High-temperature stability: The chokes are designed to operate at temperatures ranging from -40C to +125C, providing reliable performance even in extreme conditions. Low profile, just 32mm: The chokes are designed with a low profile, making them easy to integrate into existing systems and reducing the overall size of the charging system. High reliability: The chokes are designed to meet strict automotive AECQ200 industry standards for reliability, ensuring that they will perform consistently over time.
The 4CMCN065R0-16H and 4CMCN065R0-32H chokes represent a significant step forward in developing onboard chargers for electric vehicles. Their compact size, high efficiency, and versatile design with potential customisation 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 CoolMag.
