A printed-type R＇coil functioned as acurrent sensor coupling with the measured current bus and forming magnetic linkage was designed in this paper, and the influence characteristics between the structural parameters of the board and the electromagnetic parameters of the printed-type R＇coil have been analyzed. The important influence factors on the equivalent inductance of the integrated sensor were also summarized. Characteristic curves of the impedance and phase both of the single printed board coil and two series coils were presented. Self-resistance, self-inductance and stray capacitance curves of both the single printed board coil and two series coils were analyzed. The judgment method for the results validity was proposed. The sensor centered on the printed board structure was proposed to measure the discharging current of the pulse power source. Experimental results verify the truth of the design principles and methods of the integrated coil with good dynamic property. The integrated coil can be integrated with the post process circuit unit and the detective coil sensor.
