The DC modular system places a negative resistance load on the DC power system to which it is connected.
The L/R ratio in the DC power system determines if the power system voltages and currents are stable with the negative resistance load of the modular system.
If the L/R ratio becomes too large, high transient voltages or oscillation might result and lead to unreliable system operation or to damage to the modular system power supplies.
To ensure stability of the DC power system with the modular system at maximum load, use a maximum L/R ratio of 2 microhenries per milliohm for the DC power distribution design. When L/R exceeds 2 microhenries per milliohm, you might need to add capacitors or capacitor-resistor damping circuits at the modular system inputs to prevent power system instability.
