The Double-Output DC-DC Converter Using the Current-Fed Converter

전류환류형 DC-DC콘버터를 이용한 이중출력 회로

The current-fed DC-DC converter, which is known as the most stable DC-DC converter, has a two-winding reactor in series with the input. In this paper a new double-output DC-DC converter circuit, in which the 2nd winding of the reactor is creating the 2nd output, while the 2nd winding is feeding the energy to the input in the current-fed converter, is propose. The steady state characteristics of the new circuit are clarified and it is found that the maximum value exists in the 2nd output. Furthermore, regulation characteristic is analysed by 'Slope method' and the result shows good agreement with experimental value. The 2nd output voltage regulation is performed by using regulation IC. As a result, we have achieved good regulation characteristics.
