This paper describes a Direct Sensing Current Transformer (DSCTs) for the vehicle inverter system. The DSCTs was designed to measure the motor current without magnetic cores and consist of a Hall-IC and a detection wiring. The detection wiring was arranged on a power wiring of a cooling fin plate of the power module. The detection current generates the mirror current in the cooling fin plate. The mirror current generates a causes of detection error and changes the detection flux depending on the detection current frequency. The Technology of the wiring layout of Low-detection error of DSCTs in the power module is presented.
