The SKAI power electronic platform – now in its 2nd generation – comprises highly integrated motor controllers which provide the ideal powertrain solution for mobile electric and hybrid applications. Power densities of up to 20 kVA / liter provide a notable size reduction compared with other available standard motor controller products.

The systems are designed to operate with supply voltages of 24V up to 800V and with output power ratings of up to 250 kVA. The IGBT-based SKAI 2 HV motor controller operates on sintered 100% solder-free 600V or 1200V power semiconductors and it features polypropylene film DC-link capacitors. The MOS-based SKAI 2 LV motor controller uses the established SkiiP technology with a very low-inductance connection to the DC-link capacitors, driver electronics, latest generation DSP controller, current, voltage and temperature sensors. It is integrated in a waterproof IP67 enclosure.

The compact motor controllers withstand high vibration amplitudes up to 10g rms. QUASAR motor control software functionally complements the system and completes this tried-and-tested package. SEMIKRON provides engineering services to support customers in the integration of the SKAI 2 motor controller systems. Available services include, for instance, lifetime estimation, field application support, individual parameterization of motor control software etc.
