This work studies the dynamics of a single-phase full-bridge unity power factor boost AC-DC converter and develops a linear cascade resonant controller in order to meet
two control objectives: to regulate the mean value of its DC output voltage and to drain from the network a sinusoidal current in phase with the sinusoidal source voltage, i.e. keeping the input power factor close to unity. The controller has an inner current control loop with a bank of passive resonators working in parallel that contribute with a high gain to track the
desired current reference. The outer control loop takes care of the regulation of the mean value of the DC output voltage of the converter. The feedback channel of this loop includes a filter to attenuate the intrinsic oscillations of the output voltage. Some numerical experiments are included to show the good behavior of the closed-loop system.
