New: Explore Live Energy Harvesting Designs

In a previous blog post, I provided a number of Energy Harvesting example designs that could be modeled and simulated in SystemVision. These included electrodynamic, thermal and solar energy harvesting for Industrial IoT and Automotive applications. Subsequent to that posting, we added a rich new capability to SystemVision, "Live Designs".

Enabling Cloud-based Simulation for Independent and Collaborative Automotive Solutions

ON Semiconductor uses SystemVision® Cloud to offer customers a comprehensive web-based design/simulation environment. By developing VHDL-AMS product models, ON's application engineers provide cloud-based product support, including interactive schematics and application notes, tunable simulations of pre-designed solutions, and free-form application designs. Collaborative workgroups let product application engineers work concurrently with their customers in private design workspaces, solving real design-in problems in the end-application circuit.

Motion Control Design: Frequency Response Modeling of a Flexible Structure

A versatile and effective modeling capability is available in our HyperLynx product family. It uses complex-pole fitting to extract simulation-ready models from measured frequency response data. This can be useful in a wide range of engineering design applications, from system level transfer function (signal flow) analysis, to modeling component interactions in a circuit simulation. The following example illustrates both of these aspects in a practical application: Design of a motion control loop that includes a flexible structure.

Electric Power Steering - Coordinated Control, Electronics and Motor Design

Electric Power Steering (EPS) systems provide a challenging control design problem for system integrators. Because the system directly interacts with the driver’s hands, reducing vibration is a must.

Need a Power Fairy? You Need Coordinated Electrical and Thermal Design!

A colleague of mine, a thermal design engineer, once made a comment that I’ll never forget. I was simulating a power electronics circuit and I placed a scope probe on a transistor model and plotted the power dissipation. Its value was of course changing over time, as the circuit’s operating state was varied during the simulated test scenario. He exclaimed: “You have a Power Fairy!”

Need To Tune-Up Your Network Signal Quality? Now You CAN (FD)!

Ever since the CAN specification was released many decades ago, designers have pushed their network configurations beyond the conservative limits of the standard, driven by manufacturablity, customization flexibility and other non-technical reasons. With thorough engineering analysis, including electrical simulation of the physical layer, they were able to design communication systems that meet both demanding performance and economic requirements.

Managing PWM Waveforms, Part 1 - Data Reduction

This is the first part of a three-part series on special handling of PWM waveforms. The first two parts deal with the large amount of data involved. The last part deals with precise characterization in the presence of switching cycle “noise.” I am honored to post this article, which was created by one of our talented community members, a modeling and simulation expert and my friend, Norm Elias:

Get the Heat Out! … Electronic-Thermal Design Modeling

We have recently added a number of new electro-thermal models to our Component Library. These models represent devices that are either temperature sensing/control elements, or electronic components that dissipate significant power and may require thermal analysis. These models include:

TDFS Part 3 – Impedance Measurement for Switching Converters and Power System Stability Analysis

In this final installment of my series on TDFS (Time Domain Frequency Sweep) analysis, I’ll focus on measuring impedance vs. frequency. I’ll first demonstrate the method by showing the measurement of input impedance for a switching power converter. Then I’ll extend that method to analyze the “impedance stability” of a distributed power system. Power systems may include many DC to DC converters, some acting as sources and other as loads.
