This work proposes the control of a grid-tied differential boost inverter that achieves active power decoupling of the second harmonic ripple in the power drawn from the dc voltage source.The control strategy employs partial feedback linearization, a technique that enables precise positioning of theclosed-loop poles of the linear representation of a part of the system obtained via coordinates transformation and nonlinear feedback. This approach allows for obtaining an excellent dynamicresponse in the active power decoupling control loop. The validity and effectiveness of the proposal are demonstrated through experimental and simulation results.
