Implementation of CC-CV in PSIMBattery charging systems are typically designed with the primary goal of maximizing battery health and lifespan. Among the most widely adopted strategies is the Constant Current–Constant Voltage (CC-CV) charging method. This article outlines the implementation of a CC-CV algorithm using a…
Introduction and Workflow Overview HyperStudy is a data analytic AI tool that is used to generate the data and then train a fit model of a power converter. PSIM is the simulation tool that is used to simulate the full fidelity power converter that will generate the data for the fit model. TwinActivate is the system…
Introduction A monostable multivibrator, also known as a one-shot pulse generator, is a circuit that produces a single output pulse in response to an external trigger. It has one stable state and temporarily switches to an unstable state for a defined time before returning. Commonly used for timing, pulse generation, and…
Altair® EDEM™ 2025.1 introduces powerful updates for advanced particle simulation. In collaboration with Granutools™, we have extended the EDEM calibration kit to allow users to automatically run and post-process simulations based on the well-known GranuHeap and GranuDrum standard tests, thus reducing the time and effort…
This article discusses the development of a python Graphical User Interface that runs a PSIM simulation in two stages. If you have not experimented with python on PSIM applications before, you should read the relative article here. Furthermore, this is only applicable with PSIM v2025.1 or later. If you have not installed…
This article aims to present a way to pass a variable defined in a PSIM parameter file into a Simplified C block. Let us consider a simple constant block as input to a Simplified C block and a parameter file in a PSIM simulation, as shown in following figure. Double-clicking a parameter file will open it and a user can…
DSim 2025.1 has been released to the Altair Marketplace: It includes the addition of support for UVM-3.1 and several bug fixes: Try it out and let us know what you think!
Starting with HyperWorks 2025.1, users can create, edit, and debug HW python scripts using the Altair Compose IDE. How to ? From within the HyperWorks > Developer ribbon, you have a debugger Icon that launches Compose in 2 modes: with no file loaded, where one can start to write scripts and execute them from scratch. From…
Simulation Files and tutorial PDF download link This tutorial uses EDEM 2025.1 or later EDEM versions. Liquid Bridge Model Overview: This tutorial demonstrates how to configure the Liquid Bridge Contact Model in EDEM. The model simulates capillary cohesion between particles, commonly found in applications like wet…
Skip Voltage Update Flag: This article aims to present usage of the “skip voltage update” flag in 2024. Let us consider a simple buck converter as an example to understand this feature. Here, we have made two similar buck converter circuits in which one circuit is with ideal switch and the other circuit is with thermal…
