Abstract
There are provided an apparatus and method for charging and discharging a photovoltaic PCS integrated battery applied to a system that includes a first DC/DC converterconnected to a solar cell, a DC/AC inverter, a DC link unitconnected in common to output terminals of the first DC/DC converterand the DC/AC inverter, and a second DC/DC converterhaving a bidirectional DC/DC conversion function connected between the DC rink unitand the battery. The present invention calculates the amount of photovoltaic power produced by the solar cellbased on voltage and current detected in the voltage/current detector, determines one of predetermined control modes according to the amount of photovoltaic power and the connection or not of the battery, and controls the first DC/DC converter, the second DC/DC converter, and the DC/AC inverter according to the determined control mode.
