ABSTRACT:
A method and an apparatus for power factor correction for a non-ideal load, which is supplied from a mains power supply, by a compensation device which is electrically connected in parallel with the load and has a pulse converter with at least one capacitive store. A transfer function space vector is calculated as a function of a determined mains power supply voltage space vector, a mains power supply current space vector, a compensator current space vector and of an intermediate circuit voltage which is present on the capacitive store. As a result of which the pulse converter generates a compensator voltage space vector on the mains power supply side as a function of the intermediate circuit voltage. A compensator current space vector, that keeps the undesirable reactive current elements away from the mains power supply, is thus obtained via a coupling filter that is represented as a compensator inductance.
