Hybrid Vehicle Traction Inverters

Product Brand: Arens Controls

At the heart of today's hybrid drivetrain technology is the hybrid vehicle traction inverter, designed to maximize the efficient management of high-voltage power between the power source and the drivetrain components.


Arens was among the first companies in North America to produce hybrid traction inverters specifically designed for use in commercial vehicles. Today, Arens is leading the industry in the production of automotive hardened traction inverters with power ranges from 30kW to 500kW for applications ranging from large transit buses and medium-duty trucks to hybrid passenger cars.

The new Arens POWERPAC 100kW hybrid vehicle inverter features the industry's highest power density in a compact enclosure designed to fit in the vehicle battery box. It's perfect for truck, bus, agricultural and construction equipment applications.

POWERPAC™ Traction Inverters provide vehicle OEMs with compact, high power reliability for truck, bus, agricultural and construction equipment. These Next-Generation traction inverters are the result of 10 years of product experience in the most demanding applications. With over 500 million on-road vehicle miles, Curtiss-Wright traction inverters can provide your vehicle with reliable operation for years to come.

POWERPAC™ Traction Inverters feature the highest power density in the industry coupled with industryleading Power Cycle life.

When a design passes beyond the abilities of the standard products, Curtiss-Wright’s greatest strength comes to the front with our own staff of Power Electronics Design Engineers. Over the past 12 years Curtiss-Wright engineers have worked alongside some of the biggest Vehicle OEMs to develop Traction Inverters, DC-DC Converters, DC-AC Inverters and Power Management Junction Boxes.

Curtiss-Wright works closely with Vehicle OEMs to meet design-specific criteria, and can develop other input power levels from 200VDC through 900 VDC, and output power levels including 30kVA through 500kVA. 

Curtiss-Wright works seamlessly with the selected Motor and Battery providers to integrate the traction inverter and other POWERPAC™ systems into the vehicle architecture.
