A method for controlling a switched tank converter (STC) includes (a) driving a first resonant tank circuit of the STC at a first frequency and with a first fixed on-time, to obtain a first fixed ratio of output voltage of the STC to input voltage of the STC, while the STC is powering a load having a first magnitude and (b) driving the first resonant tank circuit of the STC at a second frequency and with the first fixed on-time, to obtain the first fixed ratio of output voltage of the STC to input voltage of the STC while the STC is powering a load having a second magnitude. The second frequency is smaller than the first frequency, and the second magnitude is smaller than the first magnitude. 一种用于控制开关式储能转换器(STC)的方法包括：(a)当该STC对具有第一大小的负载进行供电时以第一频率并且使用第一固定接通时间驱动该STC的第一谐振储能电路，以获得该STC的输出电压与该STC的输入电压的第一固定比率，以及(b)当该STC对具有第二大小的负载进行供电时以第二频率并且使用该第一固定接通时间驱动该STC的第一谐振储能电路，以获得该STC的输出电压与该STC的输入电压的该第一固定比率。该第二频率小于该第一频率，并且该第二大小小于该第一大小。
