![]() ![]() In addition, the principle analysis when the converter parameters are changed is provided, and the choice of two algorithm models is compared. ![]() For various input voltages and output loads, the operating principle, optimal frequency, and efficiency are given. Moreover, it accomplishes the objective of instantly resynchronizing the algorithm after a change in the converter's parameters and starting a search for the best switching frequency in the new converter state. Additionally, the algorithm shifts between two working models to finish the search for the best switching frequency while the converter's characteristics do not change. The converter is quickly adjusted to operate at a high efficiency by sampling the input and output current values and modulating the switching frequency utilizing the algorithm. In order to address the issue of keeping the converter operating at a high efficiency level under different conditions, this paper suggests an adaptive step frequency adjustment online optimization search algorithm, which achieves the goal of fast adjustment and real-time response to parameter changes. ![]()
