| Abstract: | Based on the analysis about losses of the conventional switching mode intrinsically safe power supply,a syn-chronous Buck topology is obtained which is more efficient,cooler and safer than conventional Buck converter in intrinsically safe power supply.The parameters of this synchronous Buck topology are chosen by the rules in intrinsically safe circuits and is adopted in intrinsically safe power supply for the first time.The experimental results show that the power supply has merits of high efficiency,small... |
