High resistance power distribution circuit

The figure below shows a high-resistance power distribution circuit diagram. The significant difference between it and low-resistance power distribution is that a current-limiting resistor R1 with a certain resistance is connected in series to each branch load. Generally, the value is 5 to 10 times the internal resistance of the battery. At this time, if a short circuit occurs in a certain branch, the system voltage drop and recoil peak voltage will be small. This is because R1 limits the short circuit current and L×di/dt is also small. As shown in the figure is a schematic diagram of the voltage change between N and R. By selecting appropriate R1 and Rr, the voltage change between N and R can be within the allowable error range of the power supply system, so that the loads of the system are independent of each other and do not affect each other. The use of multi-shunt has the purpose of improving the reliability of the communication system. In practical applications, multi-level high-resistance power distribution applications can be evolved.
