Arm Balance Control Scheme of Novel Isolated Modular Multilevel Converter (I-MMC)
2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia), 2019This paper introduces an isolated modular multilevel converter (I-MMC) structure which can transport the energy power from LVDC to HVDC and HVAC with single-stage, and the arm balance control strategy. The paper also analyzes the reason of leading to the unbalance in arm, establish the relevant model, and propose the unbalance control strategy of the ...

2017 2nd International Conference on Power and Renewable Energy (ICPRE), 2017
This paper presents a hierarchical control strategy (HCS) for modular multilevel converter (MMC)-based islanded microgrid which is composed of two parts: the inner MMC control (IMC) and the outer loop control (OLC). The former includes the voltage and current control loops and the circulating current suppression algorithm, which are used to stabilize ...

Steady-state analysis of modular multilevel converter (MMC) under unbalanced grid conditions
2016 IEEE Applied Power Electronics Conference and Exposition (APEC), 2016This paper presents a steady-state analysis of the modular multilevel converter (MMC) for the second order voltage and current ripple prediction under unbalanced conditions, taking the impact of negative sequence current control into account. Using the circular relationship among current and voltage quantities, the magnitudes and initial phase angles ...

IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013
Based on pin-pointing the theoretical origin, the second harmonic current in MMC is eliminated at the source and, with it, the low frequency harmonics which proliferate from it. The implications of the elimination to MMC HVDC and MMC STATCOM are discussed.

A novel SVPWM technique for capacitor voltage balancing in modular multilevel converters(MMCs)
2017 11th IEEE International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG), 2017This paper proposes a novel space vector pulse width modulation (SVPWM) technique to address the capacitor voltage balancing issue in MMCs. The MMC topology consists of cascade connected identical and individual controllable submodules (SMs) to generate higher level output voltages.
