Abstract
A power converter including a rectifier stage connected to plural phases of a network delivering an input current at a determined fundamental frequency, a DC power supply bus and a bus capacitor connected to the DC power supply bus. The converter includes a controlled current source situated on the DC power supply bus, the current source making it possible to control a rectifier current, flowing on the DC power supply bus, and a controller for the controlled current source to control a rectifier current, flowing on the DC power supply bus. The controller is configured to implement a regulation loop into which are injected a first harmonic and a second harmonic synchronized respectively at six times and twelve times the fundamental frequency of the input current delivered by the network, the amplitude and phase of these harmonics being determined to limit the THDi and the PWHD.
