Abstract

Disclosed are method for converting a voltage and a converter for performing the same, in which power supplied from an input terminal through a switching scheme is transferred to an output terminal through a pumping scheme by means of a capacitor having small capacity, thereby improving converting efficiency and reducing shock applied to the input and output terminals. DC/AC power supplied from a power source is sequentially charged in first and second capacitors by means of a switching circuit. The power supplied from the power input terminal is dropped down and then is transferred to a load terminal through a pumping scheme. The buck-converter changes the duty or the number of pumping operations of the switching circuit so as to control the power supplied to the load terminal. In the switching circuit, the switching-on time corresponds to a period of time required for charging the capacitor. The switching circuit is maintained in an off state after the switching-on time. If the switching-off time is lengthened relative to the switching-on time, the level of voltage supplied to a load is reduced. Thus, if the switching-on time is reduced relative to the switching-off time, power supply is substantially reduced.
