| Research Abstract |
Recently, design procedure of a power electronics circuit structure is discussed for high power density circuits or thin structure converters. Then control circuits of the converter circuit may connect close to the power circuit. When the pulse current flows into the power circuit, it radiates the magnetic field and may generate near field noise voltage to the control circuit. Therefore it is important for the power electronics circuits to evaluate the near field noise voltage by experiment. This research discusses the measurement results of the near field noise voltage and the electromagnetic force voltage of a small area loop antenna from the 15 A, 100 kHz buck chopper circuit. Moreover, the noise voltage may affect the control circuits in the high power density circuits.
