Nonlinear power sharing controller for double-input H-bridge based converters

This work designs a nonlinear controller with power sharing control capability for a double input buck-buckboost converter. First it reviews the principles of operation of the buck-buckboost converter and finds the nonlinear model of this converter. Next, it proposes a Lyapunov based nonlinear controller which is adaptive against input voltage and load disturbances. Finally, it provides sufficient experimental results to verify the operation of the designed controller.
