~nth is paper a novel auxiliary power supply implaying
photovoltaic arrays is proposed. The proposed system
employs a boost converter, a bidirectional power converter
and photovoltaic arrays with predictiv
each converter. The dc output voltage
the boost converter is significantly increased against the
photovoltaic arrays output voltage variation and the load
power variation because of the load current and the PV
output current feedforward. Furthermore the bidirectional
power converter controlled by the proposed control strategy
provides the bidirectional power flow control at the ac utility
grid with unity power factor.
