This technical note introduces the working principle of an Active Front End (AFE) and presents an implementation example built with the TPI 8032 programmable inverter. The provided control model implements a DC voltage controller, cascaded with a d-axis grid current controller, as well as a unity power factor controller (q-axis current). This page also serves as…
The SS-PWM peripheral provides a specialized Pulse Width Modulation scheme (PWM) for multilevel converters, which directly integrates means for balancing series-connected submodules. Such an approach has received quick and widespread adoption, notably for Modular Multilevel Converters, Cascaded H-Bridges, and similar converter topologies. The SS-PWM block generates gate driving signals, which are dynamically assigned to suitable…
This technical note addresses the sensorless control of motor drives using a back-EMF sliding-mode observer. The technique allows speed and position estimation of a Permanent Magnet Synchronous Motor (PMSM) with surface-mounted magnets, without relying on a position or speed sensor. First, the note introduces the different categories of sensorless motor control methods. Then, the general…
This page explains how to get started with the TPI 8032 all-in-one programmable inverter. It provides an overview of the hardware architecture and detailed instructions to program the device. An open-loop voltage-source inverter example with passive loads is provided as a demo example for the TPI 8032, with a step-by-step operation procedure for users to…
This note will address specific considerations to build a custom user interface for the operation of Imperix power converters. It will focus on the main aspects to consider when operating a grid-tied converter using the OPC UA protocol. The B-Box RCP which embeds an OPC UA server can indeed be controlled with an OPC UA…
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 an induction machine, both implemented using Hardware-In-the-Loop simulation. The harmonic performance of Programmed Pattern PWM with SHE is compared to the conventional carrier-based approach by analyzing the Total Harmonic Distortion…
Imperix relies on the increasingly popular OPC UA industrial protocol to remotely control and monitor its power electronic controllers over Ethernet. To do so, the B-Board PRO and B-Box RCP controllers embed an OPC UA server to communicate with the in-house monitoring software imperix Cockpit. One of the advantages of using an open standard such…
