Power Supply System

This is a power distribution system whereby, in connection with resistive supply lines fed from an operating voltage source, successive circuits are supplied with the same constant operating voltage.

To compensate the voltage drops occurring on the supply lines, the circuits are connected to these lines via controlled transistors.

The figure shows operating voltage source V1, V2 feeding circuits I, II via supply lines 1 and 2. These lines have distributed resistors R1 and R2, so that an operating voltage reduced by the voltage drop on R1 and R2 is still available on terminals B, D of circuit II, whereas circuit 1 connected to terminals A, C is subjected to the full operating voltage V1-V2.

To compensate these voltage differences, the operating current path of circuits I and II is linked with supply lines 1 and 2 via controlled transistors T1, T3 and T2, T4, respectively, which are poled in accordance with the current direction. These transistors are controlled via additional common control lines 3 and 4 connected to their bases. To this end, these control lines which are provided with distributed resistors R3 and R4, respectively, are connected to suitably selected control voltages V3 and V4, respectively.

While the full operating currents for circuits I and II flow in supply lines 1 and 2, control lines 3 and 4 merely carry the currents reduced by the current amplification of transistors T1-T4. The layout is such that the voltage drops on res...
