| Abstract: | In this paper, the theory of waveform modification with periodical driving circuit regulation dedicated to solve the dead time problem of S.R. that occurs in some DC-DC converters is presented in this paper. By utilizing the proposed theory, the existing charge retention driving circuit is analyzed, furthermore a series of novel periodical structure adjustment circuits are constructed. The product designers can choose the appropriate one from the mentioned five various periodical structure adjustment circuits. Moreover according to the theory, other types of novel periodical structure adjustment circuits can be constructed. Both the validity and practicability of the presented theory are further verified by the experimental results. |
