摘要： PROBLEM TO BE SOLVED: To effectively suppress the propagation of high-frequency current and to reduce dimension, weight and cost required for measuring noises.
SOLUTION: In the printed circuit board 1 on which a microcomputer 2 is mounted, a current concentrator 43 is provided near a power supply connector 3 from a middle point 40 where the inductance value of a power supply wining 4 between a power supply connector 3 for supply electric power to the printed circuit board from the outside and the microcomputer 2 is halved, and a capacitor 5 is mounted between power supply reciprocating routes 41 and 42. The quantity of high-frequency current generating in the microcomputer to be propagated to a cable from the printed circuit board is reduced by 20 dB in average and 35 dB at maximum as compared with conventional packaging. Thus, effective measures for noises can be taken by the smaller number of capacitors than heretofore.

摘要： PROBLEM TO BE SOLVED: To provide a power converter with a downsized circuit capable of preventing breakage of a semiconductor switching element of energy consumption means which consumes excessive energy of a DC voltage circuit.SOLUTION: A power converter comprises: a DC voltage circuit; a rotor-side converter which converts a DC voltage of the DC voltage circuit to an AC voltage and supplies the AC voltage to a rotor wiring of a secondary exciting generator; a system-side converter which converts an AC voltage of a system wiring to a DC voltage and supplies the DC voltage to the DC voltage circuit; energy consumption means which consumes energy of the DC voltage circuit; and a voltage suppression circuit which detects and controls a terminal voltage of a semiconductor switching element. If the voltage of the DC voltage circuit increases due to inflow of excessive current from the rotor wiring side of the secondary exciting generator, the power converter turns on the energy consumption means to decrease the voltage of the DC voltage circuit to a voltage in a prescribed range. When the energy consumption means is turned off, the voltage suppression circuit suppresses a bouncing voltage when the semiconductor switching element is off.
