Abstract
En 中文
In this article, phase disposition pulse width modulation based reduced switching state multipoint clamped (MPC)-five level unidirectional rectifier has been proposed. The converter has been modeled and modulated similar to conventional MPC structured converter topologies without additional clamping diodes and flying capacitors. Besides that, the proposed topology has minimum total blocking voltage, thereby reducing losses and improved efficiency. Moreover, it enhances the system reliability, minimizes the cost, and weight of the converter system. The principle of operation, mathematical formulation, and control implementation of the proposed topology has been presented in this article. A relative comparison with existing unidirectional topologies has also been addressed. Moreover, the validated experimental results of the proposed topology have been presented along with the prototype hardware setup.
