Title:
Circuits for series voltage supply, use of such circuits and devices with such circuits
Document Type and Number:
Japanese Patent JP6348175
Kind Code:
B2
Abstract:
In a circuit arrangement for in-line supply of voltage to an electrical or electronic apparatus located in the region of a DC line, a parallel circuit of two diodes oriented in anti-parallel is arranged in the line. When a direct current is flowing between terminals of the circuit arrangement, the anti-parallel diodes permit a small voltage drop between the terminals, irrespective of the direction of flow of the current, which voltage drop is limited to the forward voltage of the diode that is currently forward biased. The voltage drop across the anti-parallel diodes is tapped by a supply subcircuit. A semiconductor switch can be connected in parallel with the anti-parallel diodes, which switch is controlled by a voltage-reduction subcircuit to minimize the power dissipation of the circuit arrangement.
