ABSTRACT:
The present invention relates to a senseless MPPT control apparatus of a photovoltaic power generation system and a method thereof. The control apparatus includes a current transformer, an A/D converter, a new and old current detector, a new duty ratio detector, an old duty ratio detector, a new and old duty ratio comparator, first and second new and old current comparators, a duty ratio adder, a duty ratio subtractor and a PWM signal generator. A maximum output point of a solar battery cell is tracked by using only one feedback current flowing into a load. Further, feedback factors can be reduced to one. It is possible to simplify the construction of a control circuit and minimize tracking control failure.
