The gamut of electronic and electrical products from low-power mobile handsets and IoT devices to electric vehicles and photovoltaic inverters is placing considerable emphasis on fast and accurate power sourcing and measurement. Companies are offering a variety of programmable power supplies and loads, plus some fixed supplies, that can be applied to the task. APEC, March 8-12 in New Orleans, will provide an opportunity for vendors to showcase their products.

“eMobility was our largest growth market in 2018 and 2019,” commented Eric Turner, managing director, EA Elektro-Automatik Inc. “eMobility includes hardware-line battery chargers, drivetrains, HV inverters, switches, cables, power-distribution systems, and batteries. We’re also seeing increased activity in fuel-cell applications.”

Turner expects to see demands for higher power density and compact unit size coupled with a rugged mechanical design with liquid cooling for harsh environments. “An increased DC voltage range up to 2,000 V will be needed for solar PV simulation, eMobility, renewable energy, and high-voltage test equipment for automotive applications,” he said. “High flexibility at the system level is needed for power scaling up to > 2 MW.”
