Overview

Simulation is paramount in power electronics because it allows us to experiment with complex converter topologies, test various scenarios, and optimize designs without the constraints of physical prototypes. It's a virtual laboratory that empowers engineers. Plecs is a powerful simulation tool with a Simulink-like interface, enabling you to simulate and visualize the behavior of various power converter topologies, allowing you to gain practical insights into their operation. The key to mastering any software is practicing examples. Therefore, Plecs simulation exercises are given to reinforce understanding and hands-on application of the concepts covered. The course is divided into the following modules:Module 1: Introduction to Power ConverterBasics of power electronics and power conversionAnalysis tools include Fourier series, total harmonic distortion (THD), power factor, average and rms value, and periodic steady-state.Module 2: Introduction to PlecsInstallation of Plexim PlecsBuilding and simulating a simple Plecs modelEditing parameters of blocksEditing scope parametersThe first electrical circuit in PlecsHalf-wave rectifier simulationUsing Plecs schematic and waveform in the reportExporting waveform as CSV data and importing it into Matlab for plottingFourier spectrum of a waveformAverage and rms valueThe hold trace option for tuning a parameterModeling of mechanical systems (optional)Module 3: Simulation Scripts in Plecs StandaloneIntroduction to Octave ConsoleSimulation Scripts environmentEvaluating parameters and exporting and importing CSV filesHolding scope trace using simulation scriptModule 4: C Programming in Plecs: The C-scriptIntroduction to C-script blockUsing parameters in C-script blockMultiplexed inputs to C-script blockModule 5: Introduction to AC-DC ConvertersIntroduction and classification of AC-DC convertersHalf-wave diode rectifier with resistive loadThe effect of inductive load in half-wave diode rectifierSingle-phase bridge rectifierHalf-wave and bridge controlled rectifier with resistive loadModule 6: Introduction to DC-DC convertersIntroduction to DC-DC buck converter and implementation in PlecsIntroduction to pulse-width modulationDesign of a DC-DC buck converterFrequency response using impulse response analysis in PlecsDesigning a feedback controller for a Buck converterThe transfer function of converter using system identificationDigital control for Buck converterModule 7: DC-AC convertersHalf and full-bridge Inverter simulation in PlecsQuazi Square Wave or Three level Inverter or Phase-shift modulationSinusoidal pulse-width modulationBipolar and Unipolar SPWMFull-bridge inverter with series resonant networksGain gain characteristics curve of resonant inverter using simulation scriptFull-bridge inverter with parallel resonant networkThree phase bridge inverter in 180 degree and 120 degree conduction modeModule 8: Texas instruments TI C2000 Microcontroller programming using PlecsIntroduction to TI C2000 microcontrollerBlink Led Using GPIOGPIO in input and output modePulse width modulation (PWM) using C2000 mcu, External mode operationTI C2000 DAC and ADCOffline simulation of TI C2000 controlling power converterOffline simulation of digital control of the Buck converter
