| Abstract(in English) | This report presents a novel circuit design for suppressing conducted common-mode noise in boost converters. We have derived an impedance-balance equation for reduction of the noise from switching devises by applying a bridge-shaped equivalent circuit to the converter. To obtain wide operating frequency range, each output terminal is connected to the circuit ground via a series circuit consisting of a capacitor and an inductor. This can provide suppression of the common-mode noise, which is caused by switching of the transistor and the diode. The EMI reduction of up to 20 dB has been obtained in the range of 1 MHz to 20 MHz with a test board. |
