A power converting apparatus for a solar power generation system includes: a power converting unit (202, 203) converting an input signal generated by a solar cell module (100) into an output signal; and a control circuit unit controlling an operation of the power converting unit (202, 203), wherein the power converting unit includes at least one transformer (216, 220), and a current sensor (223, 224) and a switching circuit (214, 215; 218, 219) connected to a primary winding of the at least one transformer (216, 220), and the control circuit unit calculates a voltage and a current of the input signal using a current of the primary winding of the at least one transformer sensed by the current sensor and performs a maximum power point tracking control so that the power converting unit is operated at a maximum power point. |
