The rectifier plays a key role in connecting generation units to a medium voltage direct current (MVDC) bus on all electric ship power systems, where the rectification systems provide power continuation warranty including power quality criteria in order to meet standard requirements. Active rectifiers are able to present distinguished benefits over passive rectifiers such as: regulation, dynamic response...
This investigation presents a current control method for an indirect matrix converter. The method, called predictive current control selects the switching state that minimizes the error in the output currents according to their reference values and, at the same time, the control scheme is enhanced by including a reactive power minimization strategy with the goal to have unity power factor in the input...
A predictive control scheme for the indirect matrix converter including a method to mitigate the resonance effect of the input filter is presented. A discrete-time model of the converter, the input filter and the load is used to predict the behavior of the reactive power and the output currents for each valid switching state. The control scheme selects the state that minimize the value of a cost function...
Current source converters are the state of art in high power applications featuring several advantages such the simplicity in the topology, the regeneration capability and the capacity to produce sinusoidal input currents. This converter features a very weak damped LC filter in the input, whose resonance frequency can be excited by the control and harmonics of the mains. In this work a new predictive...
