The self-aligned hybrid carrier-based pulse-width modulation (PWM) for modular multilevel converters (MMC) based on decentralized control is proposed in this paper. It parallel cells a submodule (SM) using PWM, which combines the concept of level-shifted PWM (LSC-PWM) and phase-shifted (PSC-PWM) methods. By implementing system digitally, carriers align themselves. Each SM interacts with other S...

A full-order dynamic model of the pulse-width modulation (PWM) DC-to-DC SEPIC converter in discontinuous conduction mode (DCM) is presented in this paper.

PWM techniques are becoming popular in the present day applications due to the control of amplitude and frequency in the output voltage from VSI. There are two popular approaches for the implementation of PWM Algorithms. Carrier based and Space Vector Approach. Both the approaches give the same performance, but due to simplicity, mostly carrier based approach has been preferred. A large variety...
