This tutorial video covers the main features of the PSIM SPICE module: - SPICE simulation setup - SPICE model import from the manufacturer - export of netlist to run with 3rd party simulator A buck converter is used as the design example. https://www.youtube.com/watch?v=04Iac1N8100
Since PSIM version 11.1 you have the ability to invoke LTSPICE from PSIM as well as to "dual define" switch models to be PSIM and SPICE compatible so that the transition between a PSIM simulation and SPICE simulation is seamless. https://www.youtube.com/watch?v=soR44B-xTeI
This tutorial covers the use of a Level 2 IGBT model for PSIM. The level 2 model is not a SPICE model and is not a piece-wise approximation. The level 2 model is derived from datasheet parameters and gives a more realistic look at gate drive and switching transitions. It is easier to use and is compatible with digital and…
AC sweeps or frequency responses in PSIM make use of switching models, so there is no need to determine the average model. You can do a sweep on simple dc-dc converters, peak current mode control, digital control, motor models, phase shift converters, 3-phase inverters, loop gain response, and input/output impedance. Any…
This tutorial video covers the new Zero-Order Hold (ZOH) element that was added in PSIM v12. This element has a new control node that allows sampling at any point in the period. This shifted sample does not impact other timings in the simulation. https://www.youtube.com/watch?v=3N7bbruJkqE
This video introduces digital delay into the plant transfer function AC sweep. With the introduction of the delay, we can see the effect on the phase of the bode plots. The AC sweep is performed with PSIM's multi-sine AC sweep, we use a buck converter and a voltage source inverter with ABC-DQ transformation as example…
Using the combined add-on Modules, SimCoder with the F2833x Target for PSIM, users can easily generate code for the floating-point F28335 DSP from Texas Instruments. https://www.youtube.com/watch?v=hpKZ83exiJ0
Added with PSIM v12 are pre-built switch modules of common converter types. Quickly build 3-phase inverters, multi-level inverters, DAB, single-phase inverters, etc. With the pre-defined flying capacitor multi-level inverters you can quickly define all of the capacitor values in one place.…
This comprehensive tutorial video goes into detail about how to set up and run a Processor-in-the-Loop (PIL) simulation with PSIM. A 3-phase inverter with Field Orientated Control is the example and is implemented on an F28335 MCU from Texas Instruments. PIL is when the compiled c code runs on the MCU and controls a PSIM…
With the PSIM DSP oscilloscope utility, you can set up runtime DSP variables to monitor or to change. The information is passed over to the SCI and the coding is handled by PSIM's auto-code generation engine. https://www.youtube.com/watch?v=UUogvZ0BLJA
