Converter Design

Quickly evaluate different topologies, switching speeds, L and C sizes, operating envelope, etc. Of course this can all be automated with our scripting or automated analysis toolboxes. Put PSIM to work for you.

EMI Analysis and Filter Design

Your converter needs to pass electromagnetic interference standards. Before you book time at the local lab, our design tools will let you compare your conducted emission versus your favorite standard and design a filter so that there are fewer surprises with the hardware.

Control Design & Implementation

PSIM can do a frequency sweep of any converter. SmartCtrl can design a controller given any frequency sweep. Put the two together and you should be able to control "anything". That frequency sweep could be an analog controller or include digital delay and discretization to design directly in the z-domain.

Our embedded control generation tools will get you going on the hardware, while you think "I didn't expect it to be this easy".

Rapid Control Testing and Implementation

Leverage a true rapid prototyping workflow with our easy to use code generation tools. Our code gen tools allow you to simulate the functionality of the code before you implement allowing for rapid changes in functionality.

Converter Design and Analysis

The requirements driving your next power supply project are very diverse while battling the main considerations of size, cost, weight, and efficiency. Technical specifications are numerous and can include operating range, load range, switching speed, control response, etc. The design constraints must always be balanced against one another. Our design tools will allow you to consider all of these trade-offs as you focus in on your final design. The well-regarded speed and robustness of PSIM will ensure that you are never fighting your simulation tools as you rapidly iterate and evaluate.

Using ideal switches is great for most simulations, but when you need to understand switching and conduction losses or a non-ideal switch transition for a particular device we have the models you will need. Read more about non-ideal switch devices.

With simulation scripting, you can automate your simulations as you verify operation across component tolerances, operating limits, and other design parameters.

PSIM is able to do an AC sweep on almost any topology without resorting to average models, this is a crucial step for the control design.

A full library of elements allows for any type of power converter or control scheme to be simulated, including non-ideal switches & non-linear magnetics.

Electromagnetic Interference – EMI – Analysis and Filter design

A working power converter is not the end of the design cycle. It must be approved for sale and one of the tests that must be passed is Electromagnetic Interference. We have developed tools to help you to analyze and mitigate your conducted emissions before you even book time in the chamber. A properly conducted EMI simulation requires non-ideal switches, parasitic inductors in the connections, and small coupling capacitors from all the major power nodes back to the ground. PSIM has non-ideal switch models that can provide a SPICE like a switch transition with a gate drive circuit. All of the parasitic inductors and capacitors can cause nightmares for other tools. Take advantage of the robust PSIM engine as it works through the simulation, and provides meaningful results.

Make use of our:

  • non-ideal switch models
  • easy to use FFT for harmonic content analysis
  • the most robust solver on the market

Control Design & Implementation

Closing the loop on a power converter can be a challenging task. Years and years of experience can help when you design controllers, or you can get the right tools for the job. We are here to help. Simulate your power converter with s-domain (analog) controllers or with digital z-domain (discrete) controllers; most importantly you will be able to simulate the difference between the two implementation methods. A common mistake done by people closing the loop is to simply translate their working s-domain controller into the z-domain and call it done; a major no-no. PSIM has the unique ability to perform a frequency sweep on almost any power converter. We provide several different frequency sweep algorithms to ensure fast and accurate simulations. Tricky simulations like LLC resonant, peak current mode phase shift full bridges, or a critical conduction mode (CRM) boost PFC are no problem to generate an open-loop transfer function bode plot.

To come up with close loop controllers, you can make use of our SmartCtrl close-loop design tool or PSIM’s link to the control design platform RidleyWorks and its impressive set of magnetics design options.

If you are doing your control design in Simulink, we also have a link to Simulink to allow you to have your control in Simulink and the power stage handled by PSIM.

Rapid Control Prototyping

More and more power supplies are making use of digital control. We have powerful design tools to help you implement and rapidly iterate your design with rapid control prototyping (RCP). A true RCP workflow makes use of embedded code generation that can be tested in simulation with the power stage; our code generation tools allow you to do this. Easily generate code for the TI C2000 family and make use of advanced PWM functionality to implement very complex PWM gating waveforms or something simple; the choice is yours. Our code generation is easy to use and requires minimal c code background.

If you do not want to make your life simple with generated code, you can insert your handwritten code and verify its operation with a simulated power stage by making use of our runtime compiler.

We have other options for the verification of VHDL and Verilog code for FPGA implementations.
