Dc/dc converter and electric generating system using solar cell having the same

An electric generating system using a solar cell, comprising:

• a DC/DC converter that converts output voltage generated from a solar cell into DC voltage and has a converter switching device;
• a snubber device that has a snubber switch clamping voltage applied to the converter switching device;
• and
• a control device that detects a phase of a power grid and controls an operation of the snubber switch according to the detected phase of the grid.

A DC/DC converter using a switching device to perform DC/DC conversion, comprising:

• a transformer that has a secondary coil inducing energy from a primary coil receiving primary current;
• a snubber circuit that has a snubber switch clamping voltage applied to the switching device;
• and
• a snubber controller that controls a turn-on or turn-off operation of the snubber switch according to a voltage level applied to the switching device.
