Abstract :
The Direct Current (DC) House is simply home that uses electrical power direct current. DC house provides methods of using renewable energy sources. By using the renewable energy sources, which are used sunlight to use a solar panels as a modifier of electrical energy. The voltage source taken from the accumulator value input and output voltages can’t change, and designed the manufacture of DC-DC Converter for DC House use Buck Converter. In this system there is the type of switching that allows the absence of losses in the transition process, but in reality there are still losses. To overcome this, the added soft-switching that serves to raise the efficiency of the switching. The voltage source used for 24V. And will produce output voltage of 12V.
