Polynomial controller for AC-DC converter with power factor correction

Authors:   Jean N. Razafinjaka, Jean Daniel Lan Sun Luk


This paper deals with the control of a AC-DC converter with power factor correction (Boost PFC). The polynomial controller named RST by the three polynomials which constitute it, R(z), T(z) and S(z), is applied to the loop voltage and the loop current is controlled by hysteresis. This kind of controller generalizes the structure of the PID one. Simulation and experimental results show that modelling the open voltage loop by a first order system gives good results supported by a THD satisfying standard IEC even the system presents nonlinearities. Teaching and industrial applications are taken into account it is the reason of using Labview with the peripheral NI 6009.
