Soft–Switching Technology for Three–phase Power Electronics Converters de D Xu

Soft–Switching Technology for Three–phase Power Electronics Converters: IEEE Press Series on Power and Energy Systems

Autor D Xu
en Limba Engleză Hardback – 3 ian 2022

Lucrarea Soft–Switching Technology for Three–phase Power Electronics Converters se adresează cercetătorilor, inginerilor de proiectare și studenților la nivel master sau doctorat, presupunând o bază solidă în electronica de putere și teoria circuitelor. Subliniem faptul că acest volum nu se rezumă la teorie, ci fundamentează tranziția de la conceptele de bază ale comutării moi la implementări complexe în sisteme de distribuție și energii regenerabile. Suntem de părere că rigoarea tehnică este punctul forte al autorului D Xu, care reușește să clasifice topologiile trifazate prin prisma eficienței energetice.

Textul explorează în detaliu familia de convertoare trifazate cu comutare la tensiune zero (ZVS) și schemele PWM Edge-Aligned, oferind o perspectivă aplicată asupra modulației vectorului spațial. Pe linia practică a volumului High-Frequency Soft-Switching Transformerless Grid-Connected Inverters, lucrarea de față extinde analiza către impactul noilor materiale semiconductoare, precum carbura de siliciu (SiC), demonstrând cum acestea pot revoluționa densitatea de putere în UPS-uri sau încărcătoare de baterii. Față de Soft Commutation Isolated DC-DC Converters, care se concentrează pe izolarea galvanică, volumul de față prioritizează sistemele trifazate și rezonanța pe partea de CC și CA.

În contextul operei autorului, dacă în Advanced Control of Doubly Fed Induction Generator for Wind Power Systems acesta se concentra pe modelarea mașinilor electrice pentru turbine eoliene, aici mută focusul pe hardware-ul de conversie care susține aceste sisteme. Abordarea rămâne fidelă stilului D Xu: o îmbinare între analiza matematică a proceselor de comutație și validarea prin prototipuri experimentale, esențială pentru inginerii R&D care dezvoltă surse de alimentare de înaltă performanță.
