Solving Coupled Power and Signal Integrity Problems

LSI Corporation uses ANSYS tools to model the behavior of a system on a chip (SOC) under load; engineers also diagnose and solve both power integrity and signal integrity issues in a single environment. LSI designs semiconductors and software that accelerate storage and networking in datacenters, mobile networks and client computing. The company developed a methodology to address power and signal integrity issues in a holistic manner by leveraging ANSYS chip–package–system solutions.

Optimizing Body-Worn Wireless Devices

Using a wireless device in close proximity to the human body creates a number of major design challenges. The radiated power of the device must be kept below levels that can create a health hazard. The device’s power consumption, size, aspect ratio and weight must be minimized to make it suitable for wearing. Yet the device must be designed to deliver a signal of sufficient power to the right location, with good reception by the target device — despite the fact that the human body may absorb a significant portion of the signal.

ANSYS Saves Time & Money When Designing PCBs

Interconnect Engineering Inc. has long used and supported ANSYS electronic design tools, this project provided the opportunity to put the new ANSYS Electronics Desktop to the test. This tool provided a major advantage in this application by reducing the amount of time required to analyze the design in both the time and the frequency domains. The Electronics Desktop integrates EM tools, circuit/system simulation, ECAD links and compliance reporting. This new technology delivers a single desktop for system simulation  design.

Multiphysics Analysis of Electromagnetic Actuators (Solenoids)

Electromagnetic actuators, or solenoids, are devices that operate by producing magnetic fields to move an armature a desired distance at a desired force. They are used in applications such as fuel injectors, power distribution (interrupters, breakers, etc.), and various automotive, hydraulic and industrial applications.

Temperature-Dependent Permanent Magnets

The demagnetization characteristic of permanent magnets is temperature dependent. Therefore, the performance of any device working with permanents magnets varies with temperature. In situations in which these devices are subject to large temperature variations, analysis must ve carried out at different temperatures to predict possible performance deterioration.Temperature-dependent permanent magnet models in ANSYS Maxwell can be applied to simulate the electromechanical performance of various devices.

Lorentz Forces in Switches and Contacts

A disconnecting switch is a mechanical switching device that is normally closed, capable of carrying currents as well as opening or closing a circuit. Disconnecting switches are not meant to open live circuits but, rather, to disconnect apparatuses at the instant when they do not carry current. However, in large electric power systems operating at high voltages, disconnecting switches are sometimes forced open due to the magnetic repulsion caused by high short-circuit currents, which is not desirable.

Multiphysics Simulation Key to Superior Traction Motor Performance

Automobile original equipment manufacturers (OEMs) face the difficult challenge of designing a new generation of traction motors — which play a critical role in hybrid electric vehicle (HEV) and electric vehicle design — by transforming electrical energy into physical energy used to turn the wheels of the vehicle. The efficiency with which traction motors can perform this conversion is critical because of its impact on the range and battery life of the vehicle.

Inductors

An inductor is a passive electric component capable of storing energy in its magnetic field. One of the basic electric components used in a wide range of applications, such as signal processing and analog circuits, it is characterized by its inductance.

Beacuse ANSYS capabilities make a broad array of studies and analyses possible, the suite offers many ways to help engineers to design, analyze and optimize inductors, from single-component performance to systems-level integration.
