The isolated bidirectional ac–dc converter is for the 380-V dc power distribution system to control the bidirectional power flow and to improve its power conversion efficiency. Here the high-side switches of the ac– dc rectifier employ IGBTs without anti-parallel diodes and SiC diodes. In addition, the low-side switches are consisting of two MOSFETs to reduce the conduction loss in the rectific...

Photo voltaic based distributed generation system has seen a wide spread interest in research community because of growing energy needs. For efficient distributed generation system, a PV cell is connected with a DC-DC converter and DC-AC inverter. Maximum power point tracking (MPPT) algorithm is used to extract maximum power from the PV cell. There are different MPPT algorithms such as perturb ...

Abstract: This paper presents an on-board vehicular battery charger that integrates bidirectional AC/DC converter and DC/DC converter to achieve high power density for application in electric vehicles (EVs). The integrated charger is able to transfer electrical energy between the battery pack and the electric traction system and to function as an AC/DC battery charger. The integrated charger to...

DC collection and transmission is one of the major development directions large-scale photovoltaic (PV) power system. In order to achieve low-cost, high-efficiency long-distance PV power, this paper adopted a grid-connected topology by using multi-modular cascaded DC-DC converters, forming an input-independent output-series (IIOS) system, LLC type converter based on IGCT magnetically integrated...

A simple step and search control strategy for extracting maximum output power from grid connected Variable Speed Wind Energy Conversion System (VSWECS) is implemented in this work. This system consists of a variable speed wind turbine coupled to a Permanent Magnet Synchronous Generator (PMSG) through a gear box, a DC-DC boost converter and a hysteresis current controlled Voltage Source Converte...

Current trends in electric power consumption indicate an increasing use of dc in end-user equipment, such as computers and other electronic appliances used in households and offices. With a dc power system, ac/dc conversion within these loads can be avoided, and losses reduced. AC/DC conversion is instead centralized, and by using efficient, fully controllable power-electronic interfaces, high ...
