ЕНЕРГЕТИЧНИ ХАРАКТЕРИСТИКИ НА ЕЛЕКТРОНЕН ТРАНСФОРМАТОР
ENERGY CHARACTERISTICS OF ELECTRONIC TRANSFORMER

Summary/Abstract: Sometimes it is necessary to work with alternating voltage, the value of which is different from the mains voltage. However, transformers and autotransformers are heavy and expensive equipment. For this reason, they are being replaced by electronic AC transformers. The function of electronic AC transformers is to provide an output voltage with a shape close to sinusoidal and with a frequency equal to the input voltage. In addition, these devices provide smooth regulation of the output voltage, zero consumption in idle mode and therefore high efficiency, low weight and dimensions, the possibility of current protection and more. The purpose of this article is to investigate the energy characteristics of a thyristor AC / AC electronic transformer.
