Design of integrated ZVS single-inductor synchronous buck converter for multiload applications

In order to suppress the cross regulation parameter which is the main problem faced by the single-inductor multi-output DC-DC converters, a new efficient converter is presented in this paper. The proposed converter includes two parameters, zero voltage switching (ZVS) and synchronization which makes the proposed converter to operate with less switching losses and switching frequency. Moreover the proposed converter reduces the coupling between the outputs obtained and the different outputs are controlled individually by using closed loop controller. This could reduce the cross regulation parameter effectively. This paper describes the theoretical aspects involved in the design procedure of the converter and the simulation results showed that this converter has better performance and highly efficient.
