POWER ADJUSTING SYSTEM AND METHOD

A power adjusting system and method are provided. The power adjusting method is applicable to the power adjusting system. The power adjusting method includes processes of: detecting an input voltage of the power adjusting system by a detector circuit of the power adjusting system; detecting voltages of first terminals of high-side switches of the power adjusting system by the detector circuit; detecting a voltage of a battery by the detector circuit; detecting currents flowing to the high-side switches by the detector circuit; detecting a current flowing through the battery; detecting a current flowing through a motor; determining whether or not abnormal conditions occur in the power adjusting system and the motor according to the detected voltages and currents, and accordingly controlling operations of the high-side switches and low-side switches and a switching circuit of the power adjusting system, by a controller circuit of the power adjusting system.
