Abstract
A method for controlling a hybrid switched capacitor (SC) converter includes (a) generating control signals for controlling switching devices of the hybrid SC converter, in a manner which regulates one or more parameters of the hybrid SC converter, (b) detecting flying capacitor voltage imbalance in the hybrid SC converter, and (c) in response to detecting flying capacitor voltage imbalance in the hybrid SC converter, generating the control signals in a manner which varies switching state duration of the hybrid SC converter, to move flying capacitor voltage towards balance.
