This paper proposes a new output current measuring method using a digital circuit and a tiny current sensor. The sensor picks up a switching current flowing through an IGBT, and can be embeded in an IGBT module. A digtal circuit based on an FPGA is used for converting the output signal of the sensor into the waveform following the output current. Experimental results verifies that the proposed method detects a dc component of the output current as well as a ripple component.
