These notes present solutions for the implementation of control software, with practical, imperix-related aspects in mind. They mostly focus on one specific subsystem and may link to other technical notes if needed. Technical notes are application-independent.
This page presents an implementation example of Selective Harmonic Elimination (SHE) using the PP-PWM modulator. This example addresses a high-power 3-level NPC inverter tied to…
This article provides some insights on the computation of optimized switching angles for use with imperix’s PP-PWM modulator. It introduces one possible approach for pre-computing…
This article aims to explore the Model Predictive Control (MPC) methodology in-depth, focusing on its operational principles, classification, and comparative analysis with conventional PID-based control….
Unlike continuous PWM, where the pulse width is modulated throughout the entire switching cycle, Discontinuous PWM introduces breaks or gaps in the modulation process. These…
This technical note provides an introduction to the LLC converter, which is an isolated DC-DC converter, popular in a multitude of fields.
The fundamental harmonic approximation is presented as a modeling technique before the operation of the LLC converter is discussed above resonance, at resonance, and below resonance.
Following that, this technical note demonstrates how to build and operate an LLC converter using imperix hardware and software, and compares the physical implementation with the theory and the simulated plant.
Simple first-step guide to building NPC converters, taking as an example a 3-phase 3-level NPC converter supplied by a DC voltage and connected to a resistive load.
This article focuses on the control of a star-connected cascaded H-bridge (CHB) using voltage balancing controllers superimposed on a state-of-the-art cascaded voltage regulator with an inner current control loop.
This technical note provides a short overview of the key factors that are essential when designing a resonant tank circuit for an LLC converter. By…
