Flying-capacitor-clamped five-level inverter based on switched-capacitor topology

2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016
This paper proposed a novel flying-capacitor-clamped five-level inverter based on bridge modular switched-capacitor topology. The inverter features the switched-capacitor circuit with step-up ability and the multilevel inverter circuit with flying-capacitor-clamped performance. With the composite structure, the number of components is cut down compared

Investigation of capacitor voltage balancing in practical implementations of flying capacitor multilevel converters

2017 IEEE 18th Workshop on Control and Modeling for Power Electronics (COMPEL), 2017
Capacitor voltage natural balancing is an attractive feature of flying capacitor multilevel (FCML) converters. However, with the commonly used phase-shifted pulse-width modulation (PSPWM), the capacitor voltages still can deviate, and active balancing is often required.

Flying Capacitors Reduction in an Improved Double Flying Capacitor Multicell Converter Controlled by a Modified Modulation Method

IEEE Transactions on Power Electronics, 2012
This paper proposes an improved configuration of double flying capacitor multicell (DFCM) converter. The main advantages of the proposed converter, compared to the conventional DFCM converter, are the doubling of the number of output voltage levels and improvement of the output voltage frequency spectrum.

A New Multilevel Inverter Based on Improved Double Flying Capacitor Multicell Inverter with Reduced Number of the Flying Capacitors

2019 7th International Electrical Engineering Congress (iEECON), 2019
In this paper, a new improved multilevel inverter topology on the basis of IDFCM topology is proposed. By adding three high frequency switches and one DC voltage sources, this topology is capable to generate number of the output voltage levels which multiplied further than two toward the IDFCM topology.

Simulation of 3-Phase 3-Level Flying Capacitor rectifier with soft start and flying capacitor voltage balancing

2023
The emergence of 600V GaN devices has led to a rise in popularity of multilevel converters for high power 800V applications. Among these converters, the Flying Capacitor Multilevel Converter (FCML) has gained traction due to its numerous benefits, including higher efficiency, lower total harmonic distortion (THD), lower electromagnetic interference ...

Observation of a flying capacitor converter

2008
A switched observer design is proposed to estimate the capacitor voltages from current measurement. Based on weak Lyapunov function, a LaSalle invariance principle is used to characterize invariant set and its associated control laws for switched systems. Application to the state estimation of a power converter is given.
