PowerCell for DC Fast Charging

One of the main requirements for the widespread use of electric vehicles is having an accessible EV charging infrastructure. Governments and industries worldwide are preparing to invest in charging infrastructures. The critical points in the product decision are costs, power and reliability. SEMIKRON offers a comprehensive portfolio of products that meet the needs of fast charge equipment from as little as 22kW right up to 450kW.

PowerCell Benefits

Our new 50kW PowerCell enables companies to market DC fast chargers using a qualified power electronics platform. Availability, efficiency and reliability guarantee fast time to market and low upfront investment costs. In combination with a secure supply chain and a modular design, the PowerCell plays a vital role in the successful deployment of your DC fast chargers.

The new 50kW PowerCell is an off-the-shelf solution for DC chargers that is scalable to meet high power charging requirements. It includes a 3-phase PFC rectifier and a DC/ DC converter with galvanic isolation for an output voltage of up to 500VDC or 1000VDC. It also includes all the necessary filters and a control unit with an interface to the charge controller.

The 50kW PowerCell meets the CCS Power Class definition for a 50kW DC fast charger. When operated in parallel it meets the HPC350 definition (380A@920Vdc).
