A Carrier-Based Discontinuous PWM for Single and Parallel Three-Level T-Type Converters with Neutral-Point Potential Balancing [PDF]
, 2021 The three-level converters have an inherent problem of the neutral-point (NP) voltage unbalance due to the split dc-link capacitors. This NP voltage unbalance degrades the output voltage/current waveform quality.

Fuzzy Second‐Order Sliding Mode Control Design for a Two‐Cell DC‐DC Converter
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 This paper presents a fuzzy second‐order sliding mode controller for a two‐cell DC‐DC converter. For this aim, a second‐order sliding mode controller and a type‐2 fuzzy system are combined to achieve an adequate control. For this reason, backgrounds on the type‐2 fuzzy sets and on the second‐order sliding mode control applied to discrete systems have ...
