Abstract

This work aims to identify the impact of third harmonic circulating current injection (THCCI) in a Cascaded H-bridge converter in delta configuration (Delta-CHB) for Static Synchronous Compensator (STATCOM) application. The analyses consist of evaluating the impact of THCCI on the silicon area of semiconductor devices, based on a typical IGBT/Diode model to determine the nominal current of the devices for a given maximum junction temperature. A coefficient of determination higher than 89% was obtained for all modeled variables. The results showed an increase of 42.4% in the active area of the IGBT and 42.2% in the active area of the diode when the peak cluster current increased by 62%.
