Title: Dc-dc converter
Inventor: KATO TSUTOMU
IPC: H02M3/335
Filed: 1992-02-27
Abstract: PURPOSE:To reduce the power consumption of the power source for controlling switching of a DC-DC converter. CONSTITUTION:A transistor 2 is controlled to a turned-on state by turning on a photocoupler 5 by means of a switching control circuit section 10 and transistor 4. In response to the turning-on control, a DC voltage from a power source 11 is supplied a power MOS FET 1 as a power supply voltage. After the DC voltage supplied to the primary side of a transformer 14 is converted into an AC voltage by means of the turning on and turning off operations of the FET 1, the AC voltage is rectified on the secondary side of the transformer 14. Since the voltage from the power source 11 is used as the power supply voltage of the FET 1, the power consumption of a power source 12 for controlling switching can be reduced.

Abstract: PROBLEM TO BE SOLVED: To suppress current concentration to circuit boards on an outer peripheral part, to relieve a plating increment and to ameliorate the variation in plating thicknesses by providing the central part of a multiple blank layout circuit board to be used as a cathode with a power feed point and subjecting the conductive circuit parts of the circuit board to plating by electroplating. SOLUTION: The conductive circuit parts of the circuit boards 7 connected by connector wirings 9 between the circuit boards are subjected to plating by executing electroplating with the sheet-like multiple blank layout circuit board as the cathode. At this time, the central part of the multiple blank layout circuit board is provided with the power feed point 1. The respective central parts on the two sides facing each other may also be provided with the power feed points. As a result, the resistance between the power feed point 1 and the circuit boards 7 near the same is made smaller than the resistance between the power feed point 1 and the circuit boards 7 in the outer peripheral part and the current concentration to the outer peripheral part may be averted.  At this time, the value of the ratio between the resistance from the power feed point 1 to the circuit boards 7 existing at its ends and the resistance value up to the circuit board 7 existing in the central part is preferably set at a prescribed value, for example, a range of 1.2 to 3.5.
