Regenerative electronic loads represent an efficient solution for testing power sources, as they allow the absorbed energy to be fed back into the grid, avoiding thermal dissipation. Current commercial solutions, although effective, present limitations in terms of dynamic performance. The aim of this work is the development of a DC regenerative electronic load capable of responding to current steps of several tens of amperes with settling times in the range of tens of microseconds. To this end, a complete system has been designed and simulated, including the electronic load and the inverter for feeding energy back into the grid. The system control was implemented using hysteresis regulators.
I carichi elettronici rigenerativi rappresentano una soluzione efficiente per il collaudo di sorgenti di potenza, in quanto consentono di reimmettere l’energia assorbita in rete, evi tando la dissipazione in calore. Le soluzioni commerciali attuali, seppur efficaci, presen tano tuttavia limitazioni in termini di prestazioni dinamiche. L’obiettivo di questo lavoro è lo sviluppo di un carico elettronico rigenerativo in corrente continua, in grado di rispon dere a gradini di corrente di decine di ampere con tempi di assestamento nell’ordine delle decine di microsecondi. A tal fine, è stato progettato e simulato un sistema completo, comprendente il carico elettronico e l’inverter per la reimmissione dell’energia in rete. Il controllo del sistema è stato implementato utilizzando regolatori a isteresi.

Abstract
Regenerative electronic loads represent an efficient solution for testing power sources, as they allow the absorbed energy to be fed back into the grid, avoiding thermal dissipation. Current commercial solutions, although effective, present limitations in terms of dynamic performance. The aim of this work is the development of a DC regenerative electronic load capable of responding to current steps of several tens of amperes with settling times in the range of tens of microseconds. To this end, a complete system has been designed and simulated, including the electronic load and the inverter for feeding energy back into the grid. The system control was implemented using hysteresis regulators.| File | Dimensione | Formato | |
