The widely used power supply (Switched Mode Power Supply: SMPS) as a source in order to stabilize direct current for electronics or communication systems has merits, when it is compared to the existing source for stability, such as high efficiency.<br/> small size. light weight by means of switching process of the semiconductor device which controls the flow of power.<br/> However. due to existence of inductors and capacitors used for charging energy. the source part in electronic or communication systems hasn't reached the speed. that is supposed to get. for achieving smaller size and lighter weight.<br/> In order to get smallness in size. It is ne-cessary to increase switching frequency. And that makes devices for measuring energy smaller.<br/> Nevertheless. the rise switching frequency brings increases in switching loss. inductor loss. and power loss Also. the occurrence of surge and noise caused by high frequency switching is getting higher.<br/> The resonant converter has been considered as one of methods that give solutions for the problems of SMPS and that method has been paid attention as a source technology in electronics and communication.
