摘要：
A system for measuring an output current of a DC-to-DC converter with a transistor power stage includes a voltage measuring circuit and an impedance. The voltage measuring circuit, which is connected to the output of the power stage of the DC-to-DC converter, measures an average voltage drop on impedances of the transistors of the power stage. The impedance, which is connected to an output of the voltage measuring circuit, reproduces the impedances of the transistors of the power stage and is traversed by a scaled version of the current output of the voltage measuring circuit.
