A PARALLEL OPERATION METHOD OF THE LOW VOLTAGE DC-DC CONVERTER AND PHOTOVOLTAIC CONVERTER AND AN APPARATUS FOR THIS

摘要

The present invention relates to a parallel driving method for a low voltage DC/DC converter and a photovoltaic converter. The method includes the steps of: measuring the power value required by a load side; converting the solar energy to DC power in a photovoltaic battery; transmitting the DC power converted in the photovoltaic battery to the load side through a static current circuit in the photovoltaic battery; calculating the power value transmitted to the load side by using the static current circuit in the photovoltaic battery; calculating the difference between the power value of the power required by the load side and the power transmitted from the static current circuit in the photovoltaic battery; and applying the power corresponding to the power difference to the load side from the low-voltage DC/DC converter.
