| Abstract |
This paper presents a novel concept of a DC-DC converter with high step-down of voltage. In theproposed topology the maximum voltage of the inductor is three times lower than in a buck converter. The proposed converter operates with threefold wider duty cycle than the buck at a given voltage gain. Moreover, it provides continuous regulation, low voltage stress across switches, and is adequate for bi-directional GaN transistors use. Its operation, efficiency and power losses analysis are demonstrated at 48-to-5 V and 400-to-48 V case of operation. An effective method for efficiency improvement by the use of an extended converter concept was also demonstrated. |
