PITTSBURGH--(BUSINESS WIRE)--July 10, 2001

Ansoft Corporation (Nasdaq:ANST), the leading supplier of high performance electromagnetic software for component, circuit, and system design, today announced the availability of PEmag(TM) 4.0 -- the magnetic component design software for power electronics.

The latest version of the software aids the design and analysis of power supply transformers and inductors.

The $2 billion dollar power supply transformer industry is faced with significant challenges to decrease size and increase reliability and efficiency in order to satisfy the demands of today's advanced computer and electronic equipment. To meet these demands the transformer must operate at a higher frequency. This introduces significant magnetic design issues the manufacturer did not face at lower operating frequencies. PEmag technology specifically addresses this issue.

PEmag is a customized interface for Ansoft's industry leading electromagnetic finite element technology. PEmag allows the designer to create geometry by selecting from a database of commercial cores, wires, materials and geometries and virtually build and simulate the transformer without tedious and prone to measurement error prototypes. Using the finite element solver, PEmag accurately predicts magnetizing and leakage inductance, interwinding capacitance, resistance, and other essential parameters the design engineer must consider at higher frequencies.

The new release offers a wider range of core geometry, improved library management, and improved calculation speed. "Power supply designers focus attention on the transformer design because it is the critical driver for reducing the size, cost and improving the reliability of the power supply," said Dr. Conor Quinn from Artesyn Technologies. Dr. Quinn further stated, "Traditional analysis techniques become less effective with the increasing complexity of our high frequency designs. Power supply designers need access to more advanced techniques and tools. PEmag delivers these tools in an easy to use, familiar software environment thereby bringing simulation to the forefront of the design process."
