Variable Switching Frequency for Synchronous Buck Converter
The synchronous buck converter with all three modes of operation and a closed loop controller for tracking the maximum efficiency point at all values of load current is presented in this research paper. Synchronous buck operations converter at CCM-DCM mode boundary and in DCM mode provides zero voltage switching condition for main switch. A digital closed loop controller continuously selects the optimal switching frequency for a particular value of load, which enhances the efficiency of synchronous buck converter. In this particular research paper, an algorithm for digital closed loop controller is explained and it is realized in a simulation environment. The operation of synchronous buck converter in all three modes is also demonstrated in a simulation and real time results are presented in this paper
