APPARATUS FOR POWER CONDITIONING SYSTEM OF SOLAR PHOTOVOLTAIC

摘要

The present invention relates to a power conversion device for solar photovoltaic. The power conversion device includes: a full bridge switching part which is connected to a solar panel; a transformer which converts a voltage received from the full bridge switching part and outputs the same; a diode rectifier which is connected to the transformer; a boost convertor which is connected to the diode rectifier and performs maximum power point tracking of the solar panel; and a snubber circuit part which is connected to the boost converter. The duty ratio of the full bridge switching part is 0.5. According to the present invention, the loss of a circulating current can be minimized by maintaining the low circulating current of a transformer and a full bridge switching switch.
