The Power Electronic Converters Virtual Lab is a free, browser-based simulation platform bringing together 55 interactive converter experiments in one place. From the humblest single-diode half-wave rectifier to advanced sparse matrix converters, every major topology in a modern power-electronics curriculum is available to launch, tweak and measure in real time. Each simulator draws physics-accurate waveforms and reports the quantities that matter — average and RMS voltage, ripple factor, form factor, efficiency, total harmonic distortion (THD), power factor and firing angle — so theory and practice meet on the same screen.
Master the fundamentals with the buck, boost and buck-boost converters, then explore the Ćuk, SEPIC and ZETA topologies for wide input-range designs. Class A through Class E choppers cover single-, two- and four-quadrant DC drive operation including regenerative braking.
Transformer-isolated SMPS topologies — flyback, forward, push-pull, half-bridge, full-bridge and the soft-switching phase-shifted full-bridge — demonstrate galvanic isolation, high step ratios and multi-output supplies.
Compare single- and three-phase, half- and full-wave, controlled and uncontrolled rectifiers, plus semi- and dual-converters for four-quadrant drives. Modern boost PFC, totem-pole PFC, interleaved PFC and the three-level Vienna rectifier show how near-unity power factor and low input current harmonics are achieved.
Single- and three-phase voltage-source, current-source and Z-source inverters cover SPWM, SVPWM and 120°/180° conduction. On the AC–AC side, explore phase-controlled voltage controllers, cycloconverters and 9-switch direct, indirect and sparse matrix converters.
