Self-Synchronized Common-Mode Current Control Strategy for Power Rebalancing in CPS-PWM Modulated Energy-Storage Modular Multilevel Converters

Capacitor voltage imbalance among submodules in energy storage modular multilevel converters (MMCs) can lead to current distortion, power oscillations, and even system instability.

Analysis of total harmonic distortion and power consumption in AC to AC voltage convertor using integral cycle PWM control for fast pyrolysis

2015 International Conference on Computer, Communications, and Control Technology (I4CT), 2015
Renewable energy production by pyrolysis is gaining greater interest. A 240AC is used to power up the furnace to heat up fixed-bed reactor. An analysis is important for the power consumption and total harmonics distortion on the specified pulse width modulated (PWM) phase control per cycle of the incoming 240AV supply.

A new optimal programmed PWM technique [for power convertors]

Proceedings of Second International Conference on Power Electronics and Drive Systems, 2002
The paper presents a new method-optimal programmed PWM (OPPWM) technique-which further reduces the harmonic distortion (THD) of the surplus power converter harmonics than those of conventional programmed PWM (PPWM) techniques and ameliorates the amplitude frequency spectrum distribution of the surplus harmonics. The scheme not only inherits many merits

Discussions on control loop design in average current mode control [PWM DC/DC power convertors]

Conference Record of the 2000 IEEE Industry Applications Conference. Thirty-Fifth IAS Annual Meeting and World Conference on Industrial Applications of Electrical Energy (Cat. No.00CH37129), 2002
Large control output ripple in ACMC (average current mode control) PWM DC/DC converters exposes challenges in accurate modeling and design. In this paper, superposition models are utilized to perform control design analysis for ACMC PWM DC/DC converters.
