Abstract

An inverse adaptive control scheme for sinusoidal generation in a DC-DC switching boost converter is presented. The control block resulting from the identification of the inverse model of the converter, is implemented by means of IIR filters whose coefficients are adapted through an LMS algorithm. Simulation results of the sinusoidal output voltage with a total harmonic distortion lower than 2.5% are provided to validate the design
