![]() ![]() PLECS: Thermal Simulation of a Buck-Converter Since the focus of this exercise is on modeling the switching converter rather than the control system, the forward converter is operated in open-loop control mode with a fixed duty cycle. During the exercise the user creates a detailed model of a two-stage power electronic converter including a single-phase input rectifier and an output forward converter. This tutorial introduces the user to the basic working principles of PLECS including the top-down modelling approach and basic user interface interaction. PLECS: Modeling a Switched-Mode Power Supply The user will also learn how to create a subsystem for organizing the model, implement controls for a multi-domain system, and use the Probe block to monitor component signals as an alternative to using meters and sensors. A further iteration demonstrates that the PLECS environment can be directly interfaced to the Simulink one so that the complete model can be comprised of blocks in both. Then a simulation can be run and resulting schematics and waveforms are provided for comparison. The instructions explain how to use the component libraries to model a system in the PLECS workspace, as well as how to interconnect components and parameterize them. This tutorial introduces the basic concepts of PLECS Blockset by having the user build up a simple passive network and a buck converter circuit in a PLECS Circuit block within a Simulink model. ![]() This tutorial introduces the basic concepts of PLECS Standalone by having the user build up a simple passive network and a buck converter circuit. ![]()
