SKAI Multi Converter System

Semikron offers SKAI technology. The technology consists of MOSFET LV system that is suitable for application in material handling equipment and electric vehicles. The IGBT HV system is suitable for application in fully electric vehicles and hybrid vehicles. The SKAI Multi converter system is suitable for application in auxiliary supplies for commercial vehicles. The SKAI multi converter system is a high-level-integration power electronics system that comprises multiple converters used to control electric current flow under harsh ambient conditions. Different operating modes are possible. The system, for example, can be supplied with electric power by way of a 3-phase generator or an HVDC bus. The system is housed in a water-cooled case (IP67 protection rating) and communicates with the vehicle master controller via a CAN bus. The integrated semiconductor components come from Semikron's tried and tested MiniSKiiP family (2nd generation). The signal interface features analogue and digital I/Os to allow for the connection of a wide variety of sensors. Temperature sensors and resolver inputs for example. The multi-converter system has a total of four power converters: Converter I – 3-phase 40 kVA active front end converter, Inverter II – 3-phase 20 kVA drive inverter, Inverter III – 3-phase 10 kVA drive inverter, and DC/DC converter – 14 V/300 A or 28 V/165 A.
