PLECS: Advanced Power Electronics Applications with examples

Explore scalable converters from two-level to multi-level and multimodular architectures, learning how higher levels improve sinusoidal output and reduce harmonics. Assess balancing, cost, and grid applications like renewables and HVDC.

Explore the design and control of a three-level neutral-point-clamped grid-connected inverter in a plecs model, using a decoupled d-q current controller with pll and a dc-link voltage loop.

Explore the design and control of multimodular converters in Plex, focusing on modular topology, scalable submodules, and open-loop voltage control for high-voltage, low-harmonic outputs.

Understand back-to-back converters for HVDC, linking a rectifier and inverter by a DC link, with active and reactive power flow controlled by phase offset, and explore real-world HVDC links.

Explore a three-phase grid-connected rectifier using an active front-end with phase-shift control, employing a six-thyristor bridge to convert AC to DC and enable HVDC back-to-back topology.

Explore grid-connected HVDC and bidirectional four-quadrant operation with back-to-back thyristor bridges and a DC link capacitor, enabling power flow between Norway and Denmark through firing-angle control and phase difference.

Discover how motor drives use power converters with field oriented control to convert torque and speed through dq axes, and why space vector modulation improves power quality and dynamic response.

Demonstrate sensorless field oriented control of a permanent magnet synchronous motor with a diode rectifier and IGBT converter, using DQ frame and space vector modulation.

Examine Plex's mechanical library by mapping inertial, damping, stiffness, and gearing to electrical analogs in a front-wheel electric vehicle demo with a six-to-one gearbox.

Explore Plex magnetic library by building an ideal to non-ideal transformer, analyzing saturable core behavior with field strength h and flux density B, and plotting saturation curves for design insight.

Prepare PLECS models for RT box analysis by building real-time hardware in the loop and software in the loop tests using PWM capture and PWM output across multiple model examples.
