Abstract
A switch control method is applied to a hybrid voltage converter including a switched capacitor unit and a freewheeling unit. The method including obtaining the output current of the hybrid voltage converter, when the output current is greater than a first current threshold, controlling the switches in the hybrid voltage converter to operate in parallel conduction mode, when the output current is less than the first current threshold, controlling the switches in the hybrid voltage converter to operate in sequential conduction mode. When the switches operate in parallel conduction mode, N switches in the switched capacitor unit are controlled to turn on and off with the same duty cycle and a phase shift of 360/N degrees. When the switches operate in sequential conduction mode, each switch in the switched capacitor unit is controlled to conduct individually with the same duty cycle in sequence.
