چکیده
Simple control of a stand-alone variable speed wind turbine with permanent magnet synchronous generator (PMSG) is presented in this paper. PMSG fed different types loads by means converter where switched mode rectifier connected to the PMSG, boost DC-DC converter, and voltage source inverter (VSI). The operated at measured it tested estimated which based on power calculation power, generating electric losses dynamic during variation speed. estimation would provide scope what method applicable practice increase performance scheduling loads. bidirectional battery charger controlled used shortage implemented an embedded system using STM32-based microcontroller. During or fluctuation speed, load within acceptable limit, has been compensated. An extensive simulation conducted MATLAB/Simulink, shows good response decrease

متن کاملA Bi-Directional DC/DC Converter for Energy Storage Systems
This paper addresses a bi-directional dc/dc converter suitable for an energy storage system with an additional function of galvanic isolation. An energy storage device such as an electric double layer capacitor is directly connected to one of the dc buses of the dc/dc converter without any chopper circuit. Nevertheless, the dc/dc converter can continue operating when the voltage across the ener...
متن کاملA Fhase-Shift Controlled Bi-directional DC-DC Converter
The newly developed phase-shift controlled bidirectional DC-DC converter has the conventional features of phase-shifted converters, including zero-voltage switching (ZVS) and constant switching frequency. However, it has been improved by developing a bi-directional power flow capability and applying synchronous rectification, hence the on-state voltmge drop of the active devices are small.
متن کاملA Unified Dynamic Model for Bi-directional DC-DC Converter
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, ...
