Inflow Analysis in Converter Device in Air Conditioner 1 PK in the Room

Abstract

Inrush current is a phenomenon of surge in current that occurs at the beginning of the operation of a power converter device in an Air Conditioner (AC) system, especially at a capacity of 1 PK which is widely used in residential and office rooms. This surge of current is generally triggered by the process of charging the DC-link capacitor in the rectifier circuit as well as the initial characteristics of the compressor motor at starting. High inflow values can lead to a decrease in voltage quality, interference with the distribution system, as well as accelerate the degradation of power electronic components. This study aims to analyze the characteristics of inflow in AC 1 PK converters in closed room conditions with certain thermal loads.
