The paper presents the development of an electrical motor drive for a commercial application. Different technical solutions for the building blocks are compared regarding system performance, efficiency, reliability and cost. A frequency converter has been developed based on the results of this investigation and is introduced in commercial applications. The new softPHASE 0 modules are easy-to-use components to design high efficient inverter and DC-DC converter in SoftSwing(R) resonant topology. The phase-leg concept provides the flexibility to distribute the inverter over the available volume in the application. The scalable power by paralleling multiple modules is a further advantage of the presented solution. The power modules are designed under the maxim of gaining highest power density as well as lowest stray inductances. High switching frequencies enable even special E-motors with extremely low leakage inductance to perform well. This is in particular beneficial for ultra high speed drives or motors with a high pole pair number.
