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.
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 page presents a method for selecting an inductance value for a Dual Active Bridge (DAB) isolated DC-DC converter. DAB converters can be easily constructed…
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.
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…
