Abstract: This paper deals with heatsink design and verification of IGBT-based full-bridge converter of rated power 150 kVA. The converter is designed for air cooling-based installation of total power 1.35 MVA operating in medium-voltage power system. In order to exactly determine the cooling ability of the designed system, dc current analysis has been applied to IGBT modules connected in series.
