Optimal Decoupled Discontinuous Modulation for StatComs Based on the Cascaded H-Bridge Converter
IEEE Transactions on Industrial ElectronicsConventional discontinuous pulsewidth modulation (DPWM) strategies for cascaded H-bridge static compensators suffer from poor inter-phase capacitor voltage balance control during unbalanced grid voltage conditions. Specifically, the logic-based algorithm

Discretized Discontinuous Modulation Strategy for Cascaded H-Bridge StatCom
IEEE Transactions on Industrial Electronics, 2023This article proposes a discontinuous modulation (DM) scheme for cascaded H-bridge static compensators with star configuration. The proposed DM scheme guarantees zero steady-state active power in each converter phase arm, even in the presence of severe ...

Thermally Compensated Discontinuous Modulation Strategy for Cascaded H-Bridge Converters [PDF]
IEEE Transactions on Power Electronics, 2018 A widely adopted multilevel converter topology is the cascaded H-bridge (CHB), as it can provide voltage and power scalability. However, since the CHB converter can be composed by cells with different remaining lifetime, it could be useful to delay a ...

Carrier-based discontinuous modulation for interleaved inverters
2016 IEEE 7th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2016This paper presents a new method of carried-based discontinuous geometric modulation approach for three-phase voltage fed converters with multiple magnetically coupled legs. The proposed modulation technique produces multilevel equivalent PWM line-to-line output voltages with a reduced harmonic distortion, allows circulating current control and ...

Abstract Discontinuous modulation functions called crenel and saw-tooth have been developed for description and refinement of strongly modulated crystal structures with abrupt changes of modulation parameters. Although used for refinement of many modulated structures and mentioned in books on aperiodic crystals, technical details of such

An improved discontinuous modulation for three-level inverter
2015 9th International Conference on Power Electronics and ECCE Asia (ICPE-ECCE Asia), 2015This paper proposes an optimized space vector modulation method for the switching loss reduction of the Neutral-Point-Clamped Three-Level Inverter (NPC-TLI). The main contributions are: 1) several different sequence patterns of the space vectors are compared and an optimized sequence pattern with low switching loss and low current THD is selected; 2) a
