ANSYS 16.0 Targets Electromechanical and Power Electronic Design

Vehicle electrification, renewable energy, and power delivery applications continue to be major trends driving innovations in the industrial, automotive and aerospace sectors. “Good old designs” of power systems and electrical machines using a build-and-test methodology are out of date. Products using the old approach are filled with inefficiencies, are over-designed, and do not include electronic controls. These applications such as automotive electrification, automotive infotainment, and power electronics across many industries are driving the need for new ways of thinking and new design flows. ANSYS 16.0 delivers!

ANSYS 16.0 has significant new advancements in the design of electric machines, wireless power transfer and planar magnetic devices. For the electric machine market, we introduced a new design flow for thermal analysis of machine; advanced technology to predict core loss on laminated topologies; and new techniques to extract reduced order models from finite element solutions to circuit simulations that enhance Maxwell’s Software in the Loop (SiL) capability. Similar techniques are used to extract e-models from finite element solutions to be used as part of the e-drive real time simulation platform that enhance Maxwell’s Hardware in the Loop (HiL) capability. New Maxwell solver technologies including calculation of vector hysteresis and core loss in laminated structures, hysteresis model-based magnetization and enhanced reduced order model extraction from transient solvers extend ANSYS’ lead in electric machine design.

Additionally, ANSYS is introducing a new coupling between ANSYS RMxprt and the third-party Motor Design Ltd. package MotorCAD (template-based analytical thermal solution for electric machine design), providing a unique electric machine design solution for electromagnetic and thermal analysis of electric machines.

planar magneticsThe design of planar magnetic devices is of increasing interest to designers of LED displays, power supplies and other power electronic applications. Planar magnetic devices offer several distinct advantages over their conventional counterparts. The magnetic cores used with planar devices have a significantly reduced height (low profile) than conventional cores used with helical windings, making them ideal for today’s high density electronics.

Compared to a conventional magnetic core of equal core volume, these devices offer improved heat dissipation capability, greater magnetic cross-section area, enabling fewer turns, smaller winding area, lower leakage inductance resulting from fewer turns and interleaved windings, less AC winding resistance and excellent reproducibility. However, the design of these components is a complex process requiring a non-intuitive selection of the core, air gaps and winding setup. In addition, these components can be a considerable heat source and cause EMC/EMI issues causing further design challenges as they are integrated on PCBs.

ANSYS 16.0 delivers the capability you need to successfully design planar magnetic devices and integrate at the PCB level. ANSYS 16.0 delivers new capability for system design, investigation of magnetic and electric field effects including a look at nonlinear and temperature/frequency dependent materials, proximity effects, eddy currents, eddy and hysteresis losses, EMI analysis and the thermal impact on overall system performance.

ANSYS 16.0 offers major advances for designers of electromechanical and power electronic devices and systems. Learn more about ANSYS Maxwell Planar Magnetics Component Design capabilities by attending this free webinar on Thursday, March 26.
