An adaptive passivity-based controller for a unity power factor rectifier

“…The value for I d should be calculated by the controller in order to accomplish the following objective, 2) The DC component of the output capacitor voltage x 2 0 should be driven to the constant reference value x 2 0d , where x 2 0d > E in order to have boost behavior [2].…”

Abstract-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.

Abstract-An interconnection-and-damping assignment passivity-based control (IDA-PBC) for a full-bridge rectifier is presented in this paper. The closed-loop system performance fulfils unity power factor in the ac mains and output dc voltage regulation. The controller design takes advantage of the generalized state space averaging (GSSA) modeling technique to convert the quoted nonstandard problem (in actual variables) into a standard regulation one (in GSSA variables). In this approach, the output current is the measured signal instead of the line current; therefore, the number of sensors does not increase in comparison with traditional approaches. The whole system is robust with respect to load variations.Index Terms-AC-DC converters, generalized state space averaging (GSSA), passivity-based control (PBC).
