7-level Cascaded H-Bridge (CHB) Inverter

7-level Cascaded H-Bridge (CHB) Inverter

This model implements a 7-level Cascaded H-Bridge (CHB) Inverter for both single-phase and 3-phase systems. The 7-level output is achieved by cascading three H-bridge cells per phase, each supplied by an isolated DC source ($100V$). The model demonstrates the characteristic "staircase" waveform and explores the critical role of carrier synchronization in 3-phase configurations.
