Abstract
A biphasic Dickson switched capacitor converter includes an auxiliary circuit, a first branch and a second branch, the auxiliary circuit is connected between the first branch and the second branch, and electric charges at one of the first branch and the second branch are transferred to another of the first branch and the second branch by controlling the auxiliary circuit during a dead time when primary power transistors are turned off to realize the primary power transistors turn on at zero voltage and reduce a switching loss.
