This paper investigates feasibility of a current source converter (CSC) for battery energy storage applications. An inherent feature of the converter is boosting of the DC-link voltage. We discuss the converter operation principle and choice of circuit parameters with effects on system performance. A model that includes switching harmonics is derived to predict accurate behavior of various voltages...
Charging or discharging of batteries connected to the grid usually requires bulky capacitors on the battery side to filter out the large double grid frequency current ripple. This paper proposes a novel single phase ac-dc bidirectional (BD) converter that improves the utilization of the filtering capacitor by actively steering the ripple into it and thereby cycling it through a large portion of its...
As EVs are becoming increasing popular, the focus is to implement both efficient and cost effective power interfaces for charging EVs. This paper proposes a new power controller for charging EVs using Inductive Power Transfer (IPT) technology. The proposed control philosophy allows for charging multiple EVs while sharing power capability of the charging system according to tariff and without any direct...
This paper presents a new topology for tapping power from HVDC transmission lines. The proposed series power tap is implemented using a modular approach and IPT technology. Simulated results of a 1.8 MW series tap on a 533 kV DC transmission line are presented to demonstrate the viability of the proposed concept. Results indicate that the concept is attractive and, particularly, overcomes the technical...
The ever increasing demand for energy has led towards distributed renewable energy generation systems. Such systems depend on a well integrated information and communication infrastructure for interconnection and integration of various energy sources, loads, and environmental sensors to achieve intelligent distributed control and management. This paper describes the design and implementation of an...
Bidirectional Inductive Power Transfer (IPT) systems are high order resonant circuits and require relatively sophisticated control strategies to regulate the power flow. The control of multi-pick-up IPT systems is more challenging as the order and complexity of the system increase with number of pick-ups. This paper proposes a new controller to regulate the power flow in both directions in multi-pick-up...
Depletion of fossil fuels and growing concerns about climate change have resulted in an increasing trend towards the use of sustainable technologies such as electric vehicles (EVs). As a result, effective means of charging EVs and managing EVs has become one of the most researched topics in the past few years. Among the many solutions proposed, inductive power transfer (IPT) systems, especially bi-directional...
Bit-Stream based control, which uses one bit wide signals to control power electronics applications, is a new approach for controller design. A complete Bit-Stream based control system for a Doubly Fed Induction Generator (DFIG) is proposed in this paper to demonstrate an entirely hardware-based control system for DFIG applications. A new supervisory control system is proposed to provide excitation,...
