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.

Fuzzy Controller for Flying Capacitor Multicell Inverter

2016
This article provides the analysis of flying capacitor multicell inverter with different levels, which shows that the THD decreases with the increase in number of levels. The topology called flying capacitor multicell inverter is an inverter which has the property of natural balancing of capacitors available in between each cell, this property of ...

Capacitor Voltage Balancing Schemes in Flying Capacitor Multilevel Inverters

2007 IEEE Power Electronics Specialists Conference, 2007
This paper focuses on the development of capacitor voltage balancing methods in a flying capacitor multilevel inverter (FCMLI). Three such strategies have been described and have been applied to a five-level CMLI. The sinusoidal pulse width modulation technique has been used while making the proposals.

Constant Effective Duty Cycle Control for Flying Capacitor Balancing in flying Capacitor Multi-Level Converters

2018 IEEE 19th Workshop on Control and Modeling for Power Electronics (COMPEL), 2018
One of the challenges of utilizing Flying Capacitor Multi-Level (FCML) converters is the flying capacitor balancing. Poorly balanced flying capacitors increase the switch voltage stress, which is detrimental to performance and device rating requirements.

A 48V:2V flying capacitor multilevel converter using current-limit control for flying capacitor balance

2017 IEEE Applied Power Electronics Conference and Exposition (APEC), 2017
This work explores the well-known challenge of achieving voltage balance of capacitors in arbitrary (N-level) flying capacitor multilevel (FCML) converters. In particular, we explore the relationships among measurable circuit waveforms and flying capacitor voltage ‘states’.

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.

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.

A Comparison of the Carrier-based PWM Techniques for Voltage Balance of Flying Capacitor in the Flying Capacitor Multilevel Inverter

Twenty-First Annual IEEE Applied Power Electronics Conference and Exposition, 2006. APEC '06., 2006
This paper presents the analysis and comparison of carrier-based PWM techniques for the flying capacitor multilevel inverter (FCMI). The FCMI has the natural problem with voltage unbalance of flying capacitors. This problem generates distortion of output voltage and load current. It also causes serious breakdown of switching device.

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.
