Theoretical and experimental investigation of switching ripple in the DC-link voltage of single-phase H-bridge PWM inverters Vrije Universiteit Brussel
Direct current (DC)-link voltage ripple analysis is essential for determining harmonic noise and for DC-link capacitor design and selection in single-phase pulse-width modulation (PWM) inverters. This paper provides an extensive theoretical analysis of DC-link voltage ripple for full-bridge (H-bridge) inverters, with simulation and experimental verifications, considering a DC source impedance (non-ideal DC voltage source). The DC voltage ...

Battery voltage equalisation using single-phase cascaded H-bridge converters Vrije Universiteit Brussel
This research demonstrates modular battery storage systems’ voltage balancing using cascaded H-bridge (CHB) converters. The main principle is to maintain AC-side high-quality power absorption or injection, while on the DC-side independent battery units’ voltages get balanced. The CHB converter operates in inversion or rectification modes to discharge the storage system to an AC load/grid, or to charge it from an AC source, respectively. To ...
