CURRENT SENSING APPARATUS

摘要

The present invention relates to a current measuring apparatus comprising a voltage input part for inputting a voltage to a predetermined terminal of a power module; a voltage detection part for detecting a voltage distributed between the voltage input part and the predetermined terminal; a connection part for distributing a current of the voltage detection part to a detection terminal and the predetermined terminal of the power module; a converter for converting the current distributed to the detection terminal from the connection part into a voltage; an amplification part for amplifying an output voltage of the converter; and a current measurement part for measuring an output current of the amplification part.
