Apparatus for DC voltage power supply, comprising:
- an apparatus for providing an AC voltage output, comprising synthesizer means for generating one or more periodic output voltage signals, each said periodic output voltage signal having an output frequency, wherein the synthesizer means is supplied by an input AC voltage having an input frequency, wherein the synthesizer is configured such that each said output frequency differs from the input frequency, and
- rectifier means for rectifying the periodic output voltage signals to obtain a DC output voltage,
- wherein the synthesizer means is configured to generate a predetermined number of the periodic output voltage signals, wherein each said periodic output voltage signal is shifted with respect to another of the periodic output voltage signals by a phase given by the period of the periodic output voltage signals divided by the predetermined number.
Method for power supply with a DC voltage, comprising:
- providing an AC voltage, comprising generating one or more periodic output voltage signals using synthesizer means, each said periodic output voltage signal having an output frequency, wherein the synthesizer is supplied by an input AC voltage having an input frequency, wherein each said periodic output voltage signal is generated such that each said output frequency differs from the input frequency, and
- rectifying the at least one periodic output voltage signal to obtain a DC output voltage
- wherein generating the at least one periodic output voltage signal comprises generating a predetermined number of the periodic output voltage signals, wherein each said periodic output voltage signal is shifted with respect to another of the periodic output voltage signals by a phase given by the period of the periodic output voltage signals divided by the predetermined number.
