onsemi and Kempower enter strategic agreement for EV chargers
As part of a new strategic agreement, power semiconductor IC supplier onsemi of Phoenix, AZ, USA is to provide its EliteSiC MOSFETs and diodes for scalable electric vehicle (EV) chargers made by Finland-based Kempower. The ongoing collaboration between the two firms enables Kempower’s suite of EV charging solutions with a variety of power semiconductor technologies, including onsemi’s EliteSiC. These devices will be used in the active AC–DC front-end and in the primary and secondary DC–DC converters.
By incorporating onsemi’s EliteSiC MOSFET technology, Kempower’s EV charging solutions will benefit in terms of power, performance and reliability. With low ON-resistance and minimal gate and output capacitance, EliteSiC power devices are said to exhibit lower power losses at high operating frequencies, leading to increased system efficiency and reduced end-system size. These advantages translate into higher power density and greater overall reliability for Kempower’s EV charging solutions.
“onsemi EliteSiC power devices improve the efficiency and lower the size and weight of our EV charging solutions,” comments Kempower’s chief engineer Petri Korhonen. “In addition, onsemi’s vertically integrated supply chain and broad portfolio of intelligent power solutions give us the stability needed to continue delivering world-class EV charging solutions to the market.”
Under the strategic agreement, Kempower will incorporate the latest EliteSiC D3 diode and M3S MOSFETs into its EV charging solutions. These chargers allow for dynamic load balancing, ensuring maximum power distribution. Kempower charging solutions are cloud-connected and scalable, giving the modularity that allows fleet and charging point operators to scale their systems in line with demand.
“Our strength in manufacturing and resilient SiC supply chain assure Kempower that we will deliver high-quality products in the agreed-upon volumes today and in the future,” says Asif Jakwani, senior VP & general manager of onsemi’s Advanced Power Division. “Incorporating highly reliable power devices leads to the dependable and durable EVCs that Kempower and its customers expect every time.”
