Transformer for contactless electric vehicle charging with bidirectional power flow
2017 IEEE Power & Energy Society General Meeting, 2017This paper investigates the use of air-gap transformers in wireless energy transfer, particularly in electric vehicles. Air-gap transformers have very low coupling factor due to the length of the air-gap between the vehicle and the charging platform. A novel approach has been proposed to achieve bidirectional control of power.

Solar photovoltaic arrays are connected in series/parallel to increase the output power rating, but are desired to have lower voltage rating due to safety issues and the complexity associated with maximum power tracking of series connected cells. Because of the intermittent characteristics of PV power output, battery energy storage systems are also ...

Development of a switched-capacitor DC-DC converter with bidirectional power flow
IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 2000This brief presents a switched-capacitor dc-dc converter that offers features of voltage step-down, voltage step-up, and bidirectional power flow. Concept of energy transfer is achieved by using two current-controlled bidirectional converter cells, which operate in antiphase.

A new thyristor phase-controlled voltage source converter with bidirectional power flow capability
IAS '97. Conference Record of the 1997 IEEE Industry Applications Conference Thirty-Second IAS Annual Meeting, 1998A new line-commutated thyristor phase-controlled voltage-source power converter (VSC) with bidirectional power flow capability is proposed and studied. The proposed power converter has the same structure as the pulsewidth modulation (PWM) VSC, however, the switching devices are not self-commutated devices but line-commutated thyristors, and the ...

A bidirectional power flow rectifier with unity power factor based on instantaneous control values
The IEEE Region 8 EUROCON 2003. Computer as a Tool., 2004The paper is focused on a voltage control implementation of a three-phase rectifier (600 V/12 kVA) with unity power factor. In contrast to other known solutions based on microcomputer or DSP control, it introduces a simple control algorithm. It relies on instantaneous control values of three-phase bridge inverter that inherently performs three-phase to

This paper proposes a sensorless link voltage control method for bidirectional power flow controller for next-generation DC power network. In our previous works, we studied methods to keep the link voltage at a constant value. The methods were implemented based on feedback of the measured link voltage values.
