Abstract :
This paper proposes a method to minimize the inverter ripple by active compensation of the low frequency harmonics using a buck current source with a bang-bang control. Remain power spectrum is spreading by chaotification of the buck voltage source command using a nonlinear transfer function for the control loop. Simulation results and designing methodology are presented.
