Power Electronics for Industrial and Light Electric Vehicles
Our Solutions for Industrial and Light Electric Vehicles
More and more industrial vehicles such as forklift trucks now run on electric power. In fact, what was once state of the art for indoor vehicles, is now increasingly finding its way into outdoor vehicles, as powertrain electrification continues to advance and enter new vehicular applications. Today, power electronic systems are as commonplace in motorbikes, quads and other light electric vehicles as they are in agricultural and construction vehicles.
The SKAI 3 LV converter/inverter system is a platform solution that is designed for use in combination with existing or optimised controller systems, enabling the quick development of optimised, cost-efficient custom solutions for industrial and light electric vehicles. The compact design of the SKAI 3 LV makes it the right fit for use in industrial forklift trucks as well as in other industrial or road vehicles. More than 1.5 million SKAI 3 LV systems are in the field today.
Converter/Inverter for Electric Drive Systems
SKAI® 3 LV
Ultra Compact MOSFET Inverter Platform
SKAI 3 LV was built as a platform for low-voltage inverter systems for on- and off-road applications. This platform constitutes the 3rd generation of low-voltage inverter systems and the 7th generation of MOSFET inverter technology developed by SEMIKRON, with more than 1.5 million MOSFET inverters in the field.
To create an optimized application-specific motor control system, simply integrate a customized control board. The SKAI 3 LV platform is based on the same power-technology found in high-voltage, high-reliability applications today, providing access to high-power, maximum reliability technologies across a wide range of low-voltage on and off-road applications.

The SKAI 2 HV power electronic platform comprises highly integrated motor controllers, which provide the ideal powertrain solution for mobile electric and hybrid applications. Power densities of up to 24kVA/litre bring notable size reductions compared with other existing standard motor controller products. The systems are designed to operate with supply voltages up to 800VDC and with output power ratings up to 300kVA. The IGBT based SKAI 2 HV motor controller operates on sintered, 100% solder free 1200V power semiconductors and it features polypropylene film DC-link capacitors, all integrated into a waterproof IP67 enclosure. The compact motor controllers can withstand high vibration amplitudes up to 10gRMS.
SKAIware motor control software adds to the system function and finishes off this tried-and-tested package for the SKAI 2 HV nicely. SEMIKRON provides engineering services to support customers with the integration of SKAI 2 HV motor controller systems. Other available services include lifetime estimation, field application support, individual parameterization of motor control software, and more.
