PURPOSE:To prevent the generation of strokes by feeding the 2nd load from a point which recedes toward a power supply from the 1st load by an extent equivalent to the power supply impedance. CONSTITUTION:A voltage control circuit VC senses remotely the both ends of the 1st load Z1 and performs the constant voltage control to supply the stable voltage to both the 1st and 2nd loads Z1 and Z2. In this case, the power is supplied to the load Z2 at a point B which recedes toward the power supply from a sensing point A by an extent equivalent to the power supply impedance (r). For instance, this power supply is applied to a printed base board. In this case, a copper foil W formed on the surface of the base board is used as a resistance to supply power to the load Z2. |
