 | A shared traction drive and battery charger modes for Plug-In Hybrid Electric Vehicle application
By Mounir MARZOUK, Jean-Paul FERRIEUX, David FREY, Benoit SARRAZIN, Leonardo RUFFEIL DE OLIVEIRA | |
|
Abstract: In this article, we will focus on a 5kW three phase converter for Electric Vehicle (EV). The principleis to use the same converter for traction mode and battery charging sequences. The charger will becontrolled in PFC in order to reduce current harmonics rejections. Two types of charging mode will berealized thanks to this structure. A fast charging mode with a 3-phase double-boost, and a single phaselow power charging mode assumed by an interleaved PWM rectifier. Passive elements will bedesigned in each converter mode, with considering high frequency currents in all the designedelements. An experimental test bench has been developed in order to validate the theoretical study.The control will be implemented into a National Instruments SBRIO-9683, composed by a Power PCprocessor running a Real Time application, and an FPGA.

| | EFFECTS OF THE 2ND ORDER HARMONIC LEG CURRENT IN A MMC CONVERTER
By Mario MARCHESONI, Paolo BORDIGNON, Gianmarco MARAGLIANO, Luis VACCARO | |
|
Abstract: In this paper an exhaustive analysis of the utilization of the second harmonic component of the circulating currents in a modular multilevel converter for HVDC application is presented, with the aim of highlighting the effects on the maximum arm energy ripple, i.e. capacitors voltage ripple, and on semiconductor losses. Simulation results are presented and design remarks are indicated.

| | Lab-scale Experimental Multilevel Modular HVDC Converter with Temperature Controlled Cells
By Philip CLEMOW, Paul JUDGE, Geraint CHAFFEY, Michael MERLIN, Thomas LUTH, Timothy GREEN | |
|
Abstract: It is important to be able to produce representative experimental results when researching HVDC grids and converters. This paper reports on a lab-scale multi-level converter build. The converter was builtwith a large number of cells to enable experiments with cell balancing effects and with temperature control to investigate thermal effects and appropriate responses. The converter is able to behave as botha traditional MMC (or CTLC which is functionally similar) and as the newer AAC converter. Results are presented that show the converter is able to charge up from the DC bus and is able to function well withboth static and changing power references.

| | Performance Analysis of New Type Grid-tied Inverter - Aalborg Inverter
By Weimin WU, Zhen WANG, Junhao JI, Frede BLAABJERG | |
|
Abstract: Aalborg Inverter is a grid-tied DC/AC inverter. In order to optimize the design, its power losses areanalyzed in detail, combined with a description of the single-phase operating principle and themodulation strategy. A 2 kW / 220 V experimental prototype is constructed to verify the theoreticalanalysis. It is concluded that a minimize inductance in the power loop does help the inverter to achievethe high efficiency with the good dynamic performance
