Abstract
A multilevel self-balance control circuit can include: a voltage divider unit configured to receive and divide an input voltage; a voltage-controlled charge source load coupled to an output terminal of the voltage divider unit, and being configured to adaptively adjust charge amount input to the voltage-controlled charge source load based on an output voltage of the voltage divider unit, such that a total amount of charges flowing through the voltage-controlled charge source load during a period of each working state of the voltage divider unit is positively correlated with the output voltage of the voltage divider unit, thereby forming a negative feedback loop to achieve voltage balancing of the voltage divider unit; and a control unit configured to generate control signals for the voltage divider unit and the voltage-controlled charge source load, thereby coordinately controlling the voltage divider unit and the voltage-controlled charge source load.
