RENEWABLE ENERGY POWER CONTROL DEVICE

A renewable energy power control device may include a boost converter that receives and boosts up an input source and supplies the boosted input source to an output stage, and a control unit that controls, by using a sampling voltage of the output stage, such that the output stage does not fall below a reference voltage, and, by using a sampling voltage of the input source, such that optimal power is supplied to a charging module or additional module connected to the input source. Therefore, the charging module or additional module can use the power supply of the input source, the output stage is driven without falling below the reference voltage, the charging module or additional module is also driven, and renewable energy can be used by controlling a boost converter such that an output stage is within a reference voltage range and other modules can use the input source.
