REALIZACIJA INVERTORA 110Vdc/230V,50Hz SNAGE 70kVA U POSTROJENJU TERMOELEKTRANE
View through CrossRef
In this paper, a design of 110Vdc/230V-50Hz 70kVA single-phase inverter for uninterruptible AC power supply of critical load in thermal power plant is presented. Due to low input voltage, input current in overload conditions may exceed 1000 A which introduce significant challende during design, especially in inverter power core. In order to cope this challenge, the designer must apply creative solutions both in system and components design. This paper reveals the process of optimal power-core architecture selection, shows some important details of modular approach design and describes some mechanisms for high reliability preservation. Keypoints of physical realization are given and some recordings in testing phase are presented.
