Abstract
A PFC module is disclosed and contains an actively clocked PFC circuit () comprising at least one controlled switch (S), and an integrated circuit () as a control unit which controls during a half-wave of the input voltage(V)of the actively clocked PFC circuit () the at least one switch(S) of the actively clocked PFC circuit () with a fixed operating frequency in discontinuous current mode(DCM) The integrated circuit () sets the switch-on time (t) of the at least, one switch (S)dependent on the amplitude of the input voltage (V) of the actively clocked. PFC circuit (), and keeps constant the switch-on time (t) for at least two consecutive switching cycles within the half-wave of the input voltage (V), Also disclosed are a system containing the PFC module and a method for operating the PFC module.
