摘要： When measuring the impedance of the human body, by sending an alternating current through said body, safety specifications require the presence of a potential barrier between the power source, from which power is drawn for the current, and the human being, which can be achieved by means of a transformer. Said invention provides that, such an alternating current power supply has a positive feedback signal, such that the current delivered by said alternating current power supply is constant over greater load ranges Zx. For example, the current, sent through said human body, can be measured and the measured signal can be used for controlling the AC voltage, by means of which the transformer is excited for producing said alternating current.
