2.11.2 Connecting Multiple Loads
When output voltage regulation is critical and multiple loads are connected to the power
supply, it is important to connect each load independently to the terminals where the
output voltage is sensed. Independent leads to each load will ensure that the load
currents do not produce voltage drops in the connecting leads that could be mutually
coupled between the loads. Figure 2-7 shows two loads connected to the power
supply, with local sensing.
Figure 2-7. Multiple Load Connection with Local Sensing
If a distribution bus is utilized for multiple loads, the point of voltage sensing is important to
ensure that the voltage regulation is acceptable for all of the loads. In general, remote
sensing is used and the point of sensing is selected to minimize interaction of the various
loads through line drops caused by their load currents. Figure 2-8 shows multiple loads
connected with a distribution bus; remote sensing is used at the point where the power
leads connect to the distribution bus.
