摘要

The aim of this research is to present a novel topology of a power converter applicable in a static reactive volt ampere (VAR) compensator or a variable speed drive application. With the advent of newer and efficient topologies of power electronic converters, the requirement of a converter is to offer a performance characteristic yielding high efficiency along with a significant cost saving feature. In this direction, the resonant commutated DC link converter, the fundamental research work of this dissertation, serves the essential demands by accomplishing a resonant commutation of the intermediate DC link between the input and output converters of a system. The resonant commutation of the DC link employed here allows the usage of naturally commutated switches for the converter with lower costs compared to forced commutated devices. Further, switching losses are reduced yielding a converter of potentially higher efficiency than those available in present technology. The proposed converter can be configured in either series or parallel connection with an electric utility distribution network. Control techniques employed in the current control enable the converter to be a sinusoidal pulse width modulated (PWM) topology with harmonic elimination adopted in both the source and load currents. Experimental proof of the principle of resonant commutation of the DC link and the extensive analysis and simulation of the converter have confirmed the expected performance. A theoretical control scheme is developed for a three-phase induction motor fed with the presented converter. As an extension of the work, digital implementation of the complete topology utilizing digital signal processors (DSP) is proposed in order to optimize the speed of implementation and reduce the external hardware. Experimental study of the three-phase induction motor drive is planned.
