摘要： A power controlling method includes the following steps. A first Proportional Integral (PI) computation is performed according to an input current signal and command. Next, whether the input current signal is greater than a maximum rated charging current of a battery unit is determined to generate a switching signal for controlling a brake unit correspondingly. Then, a second PI computation is performed in accordance with the output voltage signal and a predetermined voltage command. Thereafter, the output voltage signal and the voltage command are compared to set an output current command selectively. Next, a third PI computation is performed in accordance with the output current signal and command to adjust a first pair of switching signals and a second pair of switching signals, such that a switching unit performs a corresponding switching action to adjust the output voltage signal. A power system and a power controlling apparatus are provide.
