SEMIKRON and drivetek form joint venture
SKAI power electronic system matched with motor control software for vehicles
“The QUASAR software is based on a modern, field-oriented closed-loop control system”, explains Peter Baumann, general manager of SKAItek and managing director at drivetek. It guarantees steady control of the electrical machine up to the strong field weakening range for realisation of efficient and dynamic traction drives and generator solutions. QUASAR receives input from a central controller via CAN bus and converts this precisely into a speed or torque.
The software is tailored to the control of brushless DC, interior and surface mounted permanent magnet synchronous and AC induction machines. As a standard the motor control software also offers a powerful set of additional control functions, e.g. battery deep discharge protection, overvoltage protection for DC energy recovery etc. Customer machine parameterisation and setup is easily done with the additional Q-Control software package. This PC based Windows application allows visualisation and setup of the customer system via CAN interface.
“The SKAI2 product platform is predestined for use in automotive applications owing to the use of pressure contact technology”, states Roland Mühlemann, general manager of SKAItek and business development manager at Semikron. The experience that Semikron has gained in the area of battery powered vehicles over two decades has been integrated in the SKAI product family. User benefit from this long-time experience is the availability of the SKAI platform as a standard solution.
SEMIKRON International GmbH
Semikron is an internationally leading power semiconductor manufacturer. 2011 marks the 60th anniversary of the German-based family enterprise which employs 3600 people worldwide.
