摘要： An electronic circuit device having a power wiring resonance inhibition function includes a plurality of electronic circuit elements, and a wiring board having the electronic circuit elements disposed thereon. The wiring board includes a plurality of planar power supply wires for supplying power to the electronic circuit elements. The planar power wires include a pair of planar power supply wires for supplying power to the electronic circuit elements at a predetermined voltage. The electronic circuit device also includes a plurality of damping elements disposed at a plurality of positions on the wiring board. The damping elements are connected between the pair of planar power supply wires at a plurality of positions on the pair of planar power supply wires. The damping elements reduce power supply system impedance and inhibit power wiring system resonance, thereby reducing supply voltage fluctuation caused by the power wiring system resonance and noise caused by the supply voltage fluctuation.

摘要： In a redundant configuration with multiple power sources connected in parallel to enhance reliability, a power source in which an overvoltage failure occurred has been difficult to identify and unable to be deactivated, which has impeded the improvement of reliability. However, it has become possible to deactivate selectively only the power source in which an overvoltage failure has occurred, by providing a independency-discrimination circuit that identifies the occurrence of the overvoltage failure by use of the state of a parallel operation control circuit, and connecting the independency-discrimination circuit, an overvoltage detection circuit, and a connection circuit.

摘要： A parallel power system is provided which can flexibly change output currents and the number of channels in short time and at low cost. A back board 7 of the parallel power system has connectors ECC and DCC for plug-in mounting power source circuits 1 to 6 and an electronic circuit 8. Terminals of the connectors DCC and EDC are connected by wiring lines HP. The power source circuits 1 to 3 constitute a first voltage channel by a power source line DH1 and a parallel operation control line PCH1 of the electronic circuit 8, whereas the power source circuits 4 to 6 constitute a second voltage channel by a power source line DH2 and a parallel operation control line PCH2. When a specification of the electronic circuit is to be changed, only the power source lines DH1 and DH2 and parallel operation control lines PCH1 and PCH2 are changed without changing the back board 7 and the like.

摘要： An over voltage detection circuit, which is used in a power source, a power supply system, and an electronic apparatus, includes two voltage comparison circuits. A first comparison circuit, provided for high-speed signal responses, includes voltage dividing resistors, a voltage comparator, and a reference voltage source, while a second comparison circuit, provided for low-speed signal responses, includes voltage dividing resistors, a capacitor, a voltage comparator, and a reference voltage source. The second comparison circuit, which has the capacitor, is for low-speed-signal responses and does not respond to high-speed input changes, that is, high-frequency components. The first comparison circuit, which has no capacitor, responds to any frequency components including high-speed signals and high frequency components. A high setting voltage is selected for the first comparison circuit, while a low setting voltage for the second comparison circuit.
