A Comprehensive Review of Capacitor Voltage Balancing Strategies for Multilevel Converters Under Selective Harmonic Elimination PWM

IEEE transactions on power electronics, 2021
In recent decades, applications of selective harmonic elimination pulsewidth modulation (SHE-PWM) have been extended from two-level to multilevel converters (MLCs).

Switched Capacitor Converter Based Multiport Converter Integrating Bidirectional PWM and Series-Resonant Converters for Standalone Photovoltaic Systems

IEEE transactions on power electronics, 2019
Photovoltaic (PV) systems containing a rechargeable battery as an energy buffer require multiple dc–dc converters for PV panel control and battery regulation, and hence, they are prone to be complex and costly.

A Novel Carrier-Overlapped PWM Method for Four-Level Neutral-Point Clamped Converters

IEEE transactions on power electronics, 2019
Neutral-point clamped (NPC) multilevel converters with more than three voltage levels are hard to balance the dc-link capacitor voltages, which limits their application in the industry.

PWM Switched Capacitor Converter With Switched-Capacitor-Inductor Cell for Adjustable High Step-Down Voltage Conversion

IEEE transactions on power electronics, 2019
High step-down voltage conversion is necessary to bridge the voltage gap between main power converters and low-voltage auxiliary electronics in power conversion systems. Switched capacitor converters (SCCs) are an attractive candidate as a high step-down
