LTspice Simulations for Power Electronics

This article accompanies a repository of 20 LTspice simulation templates for an undergraduate PowerElectronics course (Electrical/Electronic Engineering). The templates cover five blocks in order ofcomplexity: phase control with SCRs, phase control with TRIACs, open-loop and closed-loop DC-DCconverters, H-bridge inverters, and a multistage inverter from 12 V DC to 120 V AC. Each templateincludes an explanation of the circuit, a table of its parameters, the essential theory, the expectedresults and exercises. Some are delivered ready to simulate; others start from initial values that theinstructor recalibrates so that the student calculates, modifies and verifies
