this paper presents a novel method to calculate the reference source current and the referencecompensating current for shunt active power filters (sapfs). this method first calculates theamplitude and phase of the fundamental load current from a recursive algebraic approach blockbefore calculating the displacement power factor. next, the amplitude of the reference mains currentis computed with ...

Abstract – The current source converter represents the dual counter part to the better known and more frequently used voltage source converter. As such due to duality rules many offthe-shelf solutions concerning the VSC can be used in a modified manner to handle the CSC. This work gives a comprehensive overview of CSC PWM methods and shows how they are to be distinguished. Then based on duality...

Multi-phase (more than three-phase) converters are required mainly for feeding variable speed multi-phase drive systems. This paper discusses one such solution by using direct ac-ac converter that can be used to supply a five-phase two-motor drive system. Matrix converter based two-motor drive system is presented for the first time in this paper. Two stator windings of two five-phase machines w...

This paper presents a unified model for bi-directional DC-DC converters for both directions of power flow. The bi-directional DC-DC converter is analyzed using a seamless dynamic model with an independent voltage source and an independent current source, which polarity depends on the direction of the power flow. A small signal model is derived using a state space averaging method. Furthermore, ...
