Abstract
The present invention relates to a method for performing a mutual communication between an input stage and an output stage while performing a power transmission therebetween by using an operation mode conversion of a converter even without a separate communication line. To this end, a converter system according an embodiment of the present invention comprises: a converter for converting and transferring power between an input stage and an output stage; an input stage control unit for controlling the input stage of the converter; and an output stage control unit for controlling the output stage of the converter, wherein the input stage comprises a primary-side switch, an inductor and a capacitor, the input stage control unit may adjust the duty ratio (D) and the switching period (Ts) of the primary-side switch to adjust the number of resonances generated due to the inductor and the capacitor, and the output stage control unit may identify data transmitted by the input stage control unit according to the number of the resonances. According to the present invention, it is possible to communicate between an input stage and an output stage simultaneously with a power transfer therebetween by using an operation mode conversion of a converter without using an additional separate communication line or a wireless interface module.
