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 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 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 page covers a possible control algorithm for controlling the secondary DC voltage of a DAB converter. A working prototype is built using PEH full-bridge…
This technical note gives general insights on the implementation of coordinated control using imperix’s rapid control prototyping solutions. A grid-tied back-to-back three-phase inverter is given…
This technical note offers insights into the SS-PWM peripheral block, which is part of the standard firmware of imperix controllers. The SS-PWM block provides multilevel…
This technical note describes the operating principles of a buck-boost converter. A possible open-loop control implementation of this converter, targeting the B-Box RCP or B-Board PRO with both C/C++ and automated code…
This technical note describes the operating principles of a step-up boost converter. A possible open-loop control implementation of this converter, targeting the B-Box RCP or B-Board PRO with both C/C++ and automated…
This technical note describes the operating principles of a step-down buck converter. A possible open-loop control implementation of this converter, targeting the B-Box RCP or B-Board PRO with both C/C++ and automated…
This technical note shows how to build a decoder IP for a Delta-Sigma Modulator and establish communication with such a device through USR ports of…
What is the difference between Space Vector (SVPWM) and Sinusoidal Pulse Width Modulation (SPWM)? This article presents the advantages of the SVPWM technique over SPWM…
