Solar charging system for vehicle

A solar charging system for a vehicle, comprising:

• a first PV module;
• a second PV module serially connected to the first PV module;
• one integrated transformer directly connected to the first PV module and the second PV module to receive a surplus current from the first PV module and provide a supplemental current corresponding to the surplus current to the second PV module;
• and
• a single controller that is electrically connected to both ends of the one integrated transformer and performs MPPT control to control output of the integrated transformer to charge a battery,
• wherein the one integrated transformer includes one integrated magnetic body;
• wherein the one integrated transformer includes a plurality of primary side switches positioned and operated between the first PV module and the second PV module, and the one integrated magnetic body, and one secondary side switch positioned and operated between the one integrated magnetic body and a battery;
• and
• wherein the plurality of primary side switches is driven by one pulse width modulation (PWM) signal, and the one secondary side switch is complementarily driven with the plurality of primary side switches.
