DC-Link Capacitor Current Analysis in CHB Inverters by Hamid Hamza is a document available to read on EtoBox.
This paper presents an analytical method for calculating the dc-link capacitor current in cascaded H-bridge (CHB) inverters used for high-voltage drives. It establishes an approximately linear equivalent circuit model to derive expressions for the harmonic spectrum and root mean square value of the capacitor current, which are essential for capacitor selection. The proposed method demonstrates good accuracy through simulation and experimental results, addressing the challenges posed by the nonlinear charact
