Navitas Semiconductor announced that Exide Technologies' next-generation, high-frequency fast chargers for industrial material handling equipment have adopted new GeneSiC power semiconductors.

Exide Technologies is provider of battery storage solutions for the industrial and automotive markets. Exide's comprehensive range of lead-acid and lithium-ion solutions serves various applications, including traction batteries and charging solutions for material handling equipment and robotics, maximising fleet uptime with minimised total cost of ownership.

Silicon carbide (SiC) is a new 'wide bandgap' power semiconductor material that is rapidly replacing legacy silicon chips in high-power, high-voltage applications such as renewable energy, energy storage and micro-grids, EVs and industrial applications. GeneSiC 'trench-assisted planar-gate' SiC MOSFET technology delivers no-compromise, high-efficiency, high-speed performance, resulting in up to 25°C lower case temperature, and up to 3x longer life than alternative SiC products. With the highest-published 100%-tested avalanche capability, 30% longer short-circuit withstand time, and stable threshold voltage for easy paralleling, GeneSiC MOSFETs are ideal for high-power, fast-time-to-market applications.

Exide's high frequency chargers convert 220V AC power to a battery-level voltage between 24 and 80V for lead-acid and lithium-ion powered industrial vehicles. The 7kW module uses GeneSiC G3R60MT07D (750V) MOSFETs and GD10MPS12A (1,200V) MPS Schottky diodes, with frequency-optimised architecture. The same platform can be upgraded to 10kW, with 4 modules in parallel to provide 40kW of reliable fast-charging power.

"Exide Technologies delivers complete, carefully controlled fast-charging with close system monitoring for critical material-handling equipment, running 24/7," said Dr. Dominik Margraf, Director Product Management Motion at Exide Technologies. "Navitas' GeneSiC technology is easy-to-use, with excellent support, increased system efficiency, and cooler operation."

"Exide's 'Energizing a New World' and Navitas' 'Electrify Our World' missions are in perfect alliance," said Dr. Ranbir Singh, Navitas EVP and architect of the GeneSiC technology. "Next-gen technology drives sustainability, and of course end-user satisfaction."
