Abstract
Disclosed is a method for sensing the output current of a power source by averaging and summing instantaneous current signals generated by current sense devices installed in converters fed by the said power source.
Claims6
A method and circuit for generating a signal proportional to the output current of at least one electrical power source that feeds one or more other downstream converters, comprising:
- current sensing means for generating signals proportional to the instantaneous current in the switches or transformers or inductors windings of the said downstream converters;
- averaging and summing means to process the said signals and generate a signal that is proportional to the sum of the input currents of the said downstream converters and also to the output current of the said power source.
