Aiming the great phase lag of the control-to-output small signal transfer function of LCC resonant converter, compensation networks composed of a band-stop filter and a single-pole-single-zero network are designed. Matlab and PSpice simulations are finished simultaneously, which verify that the output voltage can be regulated automatically in the disturbance of load changing. And good steady-state...
Based on the basic modeling approach, a new small-signal modeling technique applied to the series resonant converters is presented and the models are in good agreement with the simulation and measurement results.
A single stage AC/DC converter with resonant model PFC has been deeply studied in this paper by mathematic analysis. The following results have been revealed: (1).The working conditions for the circuit have been derived and can be expressed by the formulas, which can be used to select the parameters of the circuit; (2). It has been proved that the bus voltage decreases if output power increases and...
