 Getting Started with TwisterSim Simulator With this video, you'll be introduced to TwisterSim, a unique electrothermal simulator for devices in VI power technology that allows complex evaluations with accurate dynamic simulations of load compatibility, wiring harness optimization, fault condition impact analysis, diagnostic behavior analysis, and dynamic thermal performance. Simulation results, including junction and case thermal profiles, load current and diagnostic behavior are shown on dedicated scopes views or exported in a number of different commonly used formats in just a few clicks. TwisterSim has an interactive selector that pre-selects suitable devices based on first level system requirements and it assists in describing your actual system configuration with layout, load and driving profile customization to build an accurate model of the final application. Let's try a real example of product selection and simulating its electrical and thermal characteristics using TwisterSim. Click on interactive selector button and enter your typical and maximum supply voltages, device topology, number of channels, load type, and load characteristics. A PWM source type is typically selected for LED or lighting applications where brightness control is desired or for motor applications where speed or torque control is desired. If no switching is required for the load, select DC. Now set ambient temperature and PCB dissipation area information. All information is automatically displayed by TwisterSim to pre-select suitable devices capable of meeting the requirements. Newer devices and devices that better match your conditions are reported first. The colored labels give a first feedback of expected maximum operating junction temperature. The presence of the TwisterSim logo indicates the availability of simulation models. If the selected device is among those having a simulation model, it is possible to export the selected device and application information into the simulation section. Let's select for example the N7140AS. Press the export button to proceed. At this stage you can further customize your project parameters. You can modify line-in, line-out, then DC or PWM, loads, resistors, RC load, RL load, and lamps. Simulation parameters such as duration and step size. Now it's time to press the simulation button to launch your simulation. A progress bar shows its progress status. At the end of the simulation, TwisterSim automatically opens a scope view to display the simulation results. However, a plot button becomes active as well during the simulation to check the results while the simulation is in progress. Now you can customize the data displayed in different plots according to your needs. Adding new plots, adding a new curve in a plot, adding a new function, adding a new curve, zooming an area of interest. At the end of the simulation you can save and export simulation data in different formats to facilitate result analysis. Thank you for your attention. We hope this video has helped you discover the potential of the TwisterSim Dynamic Electrothermal Simulator.
