Silicon-carbide (SiC) power electronics from STMicroelectronics has been used in ZapCharger Portable, a small electric-car charging station from Zaptec, a start-up company in the transformer industry.
ZapCharger works with any electric car on any grid. ST’s SiC MOSFET devices have enabled Zaptec engineers to design a portable, yet powerful piece of equipment. The 3kg, 45 x 10 x 10cm charger delivers an energy efficiency of 97%.
Inside the ZapCharger, 32 Silicon Carbide MOSFETs from ST deliver efficient power conversion with minimum losses.
“The key for us was to find a power technology with a very high efficiency so we could reduce the overall size of the charger without compromising performance. ST’s silicon-carbide offering was the perfect match,” said Jonas Helmikstøl, COO, Zaptec.
After successful field tests, ZapCharger is starting pilot production now, with volume ramp-up scheduled at the end of Q3 2016.
