SELF-INTEGRATION VOLTAGE CONVERTER
The invention relates to an electronic device which, fed from a sinusoidal or randomly variable network, makes it possible to supply the input of the converter with which it is equipped with a DC voltage, the receiver connected at the output also being fed with a DC voltage envelope, whereas the power factor of the current taken from the mains is kept at unitary value and said current is the image of the voltage which produces it. This device comprises a converter (12) whose high frequency output circuit loads the series circuit formed by the receiver (13) associated with impedance (16). The voltage developed across terminals of inductance (16) is rectified by bridge (15) mounted in series with the mains rectifier bridge (10) so that these voltages, added to the input of the converter (12), effect the envelope of a DC voltage, this also resulting in supplying a DC voltage envelope to receiver (13). The current taken from the mains has a unitary power factor whereas its envelope is homothetic of the voltage. This device is applicable to the majority of electronic converters used as ballasts, transformers, stabilized power supplies, and so on.
