Abstract
A current measuring device for switched-mode electronic power converters includes two independent sensors connected in series for the current to be measured, one of said sensors providing an admittance and the other providing a conductance. The current measuring device further includes a parallel current measuring resistor and an average value capacitor which are connected in parallel contribute to the provided admittance. The conductance is provided by a serial current measuring resistor as one of the sensors. The current to be measured has both DC and AC current components. The current measuring device further includes a filter is transferred back into the power path or merged with the current measuring sensors.
