A low-voltage DC-DC converter (LDC) includes: an N-phase power circuit configured by connection of N DC-DC converters in parallel between a high-voltage (HV) battery and a low-voltage (LV) battery; and one output capacitor commonly connected to an output of each phase DC-DC converter. Each phase of the N-phase power circuit is controlled in an interleaving manner which delays a phase by 360°/N. Here, each N-phase power circuit is controlled by switching at a frequency of [(a frequency at which the parasitic resistance (equivalent series resistance (ESR)) of the output capacitor is minimized)/N]. The parasitic resistance of the output capacitor of the LDC can be minimized. Accordingly, a lifespan of a battery can be improved and efficiency of the DC-DC converter can be increased through the reduction of the equivalent series resistance (ESR) of the output capacitor.

Thus, the fibrous electrode may maintain a fiber shape, and an electrical connection structure in the carbon nanotube sheet may not be damaged by deformation of the elastic fiber. That is, the fibrous electrode may be reversibly changed to maintain excellent electrical conductivity. In addition, the fibrous electrode has a fiber shape having a diameter of hundreds of micrometers, and thus the fibrous electrode may be light and may have excellent durability and excellent life span characteristics.

A fibrous electrode includes a carbon nanotube sheet which is coated on an elastic fiber and has a buckle structure. Thus, the fibrous electrode may maintain a fiber shape, may be light and small and may maintain excellent conductivity even when variously deformed. In addition, the fibrous electrode has high elasticity and thus is capable of being variously deformed (e.g., bent or stretched) and of being realized in the form of textile. As a result, the fibrous electrode may be effectively applied to flexible electronic devices such as implantable medical devices, microelectronic devices, Google glasses, smart watches, wearable computers, and smart clothing. Furthermore, a supercapacitor using the fibrous electrode includes flexible materials and thus is not easily damaged by external force such as tension or pressure. As a result, the supercapacitor may be applied to various fields because of its excellent flexibility.
