The present invention provides a voltage control method for controlling a power supply. The voltage control method comprises the following steps: obtaining a present output voltage value associated with a present gain value; obtaining a predetermined output voltage value associated with a predetermined duty ratio; calculating a target gain value, corresponding to the predetermined duty ratio, according to a gain value formula; performing a weight calculation on the present gain value and the target gain value for generating a buffer gain value; and setting an output voltage command according to the buffer gain value. Wherein the buffer gain value is between the present gain value and the target gain value.

Voltage control method

Herein disclosed is a voltage isolation circuit coupled to power supplies. The voltage isolation circuit comprises a series switch group controlled by a first control signal, a parallel switch group controlled by a second control signal, and a first high impedance element. The series switch group comprises a transistor arranged in a first current loop and having two channels connected to one of the power supplies respectively. The first high impedance element, coupled to the transistor in parallel, has a measurement terminal and two ends, connected to one of the power supplies respectively. When the series switch group is conducted, the power supplies are coupled in series in the first current loop. When the parallel switch group is conducted, the power supplies are coupled in parallel in a second current loop. Impedance values measured from the measurement terminal to each end of the first high impedance element are identical.
