This paper thoroughly examines the semiconductor power loss characteristics of modular multilevel converters (MMC). Power loss behavior is examined under different pulse width modulation (PWM) methods and operating conditions. The effects of stored energy level, circulating current control utilization, power factor and submodule voltage balancing method on power loss are studied. Furthermore, unbalanced power losses and specific semiconductor stresses within a submodule are visualized by investigating the loss distribution in a submodule. The paper aids in understanding and design of MMC converter modules, selecting PWM and control methods with power loss perspective.

A High-Performance PWM Algorithm for Common-Mode Voltage Reduction in Three-Phase Voltage Source Inverters Hava, Ahmet Masum (2011-07-01) A high-performance pulsewidth modulation (PWM) algorithm with reduced common-mode voltage (CMV) and satisfactory overall performance is proposed for three-phase PWM inverter drives. The algorithm combines the near-state PWM (NSPWM) method that has superior overall performance characteristics at high modulation index, and MAZSPWM, a modified form of the active zero-state PWM method (AZSPWM1), which is suitable for low modulation index range of operation. Since AZSPWM1 has line-to-line voltage pulse reversals...
A Scalar Resonant-Filter-Bank-Based Output-Voltage Control Method and a Scalar Minimum-Switching-Loss Discontinuous PWM Method for the Four-Leg-Inverter-Based Three-Phase Four-Wire Power Supply Demirkutlu, Eyyup; Hava, Ahmet Masum (2009-05-01) An all-scalar-control and pulsewidth-modulation (PWM) approach for the four-leg-inverter (FLI)-based three-phase transformerless four-wire power supply (PS) is proposed. The output voltage of each phase is controlled independently, and its controller is formed by a stationary-frame resonant-filter bank accompanied with proportional-control and output-capacitor current-based active-damping loops. The simple and easy to implement scalar-control method exhibits superior overall steady state and dynamic perform...
Steady-state modeling of a phase-shift PWM parallel resonant converter Iskender, Ires; Uctug, Yildurum; Ertan, Hulusi Bülent (2006-01-01) Purpose - To derive an analytical model for a dc-ac-dc parallel resonant converter operating in lagging power factor mode based on the steady-state operation conditions and considering the effects of a high-frequency transformer.
Design and Performance Analysis of a Grid Connected PWM-VSI System Kantar, Emre; Usluer, S. Nadir; Hava, Ahmet Masum (2013-11-30) Pulse-width modulation (PWM) voltage source inverters (VSIs) are favorable interface devices to the power grid for renewable energy systems. This paper deals with the design of the LCL-filter and inverter for the grid-connected VSI. A complete design procedure for both reactive and passive components of LCL-filter is demonstrated with a new iterative approach in selection of the filter inductors. The design process for a two-level VSI is clearly illustrated through an example and the dynamic response is inv...
Performance Evaluation and Selection of PWM Switching and Control Methods for Grid Connected Modular Multilevel Converters Ciftci, Baris; Hava, Ahmet Masum (2015-09-24) This paper focuses on the determination of suitable carrier based pulse width modulation (PWM) switching and control methods for grid connected modular multilevel converters (MMCs). Characterization of various level-shifted and phase-shifted carrier based PWM methods are provided in terms of output voltage waveforms both for N+1 and 2N+1 level output phase voltages. Carrier based PWM method based control approaches are evaluated for MMC. Performances of different control methods are evaluated and compared f...
