Control of Grid-connected Converters for Electric Vehicle DistributedGeneration Application

A hi-directional converter is proposed to implement the integration of electric vehicle to the grid
and household electric system. The proposed converter has two stages: a grid-connected convener. and
a dc/de converter. The grid-connected converter can operate in three modes. The first of which is a
battery charger. The grid-connected wi II control the power factor to unity and regulate the de bus
voltage and control the input current harmonics to be low. The second mode is vehicle-lo-grid mode:
the converter operates as the distributed generator inverter to feed real power back to the grid. The
third mode is vehi cle-to-home: the converter serves as a UPS to supply critica l10ads at home when the
grid has fa il ure.
