3.3 Using Multiple Power Supplies

Using two separate power supplies or both channels of a two-channel power supply to generate a higher power supply voltage can be necessary. Figure 3-1 shows an example of this configuration using a two-channel power supply to generate 50V total. For this type of configuration, the power supply outputs MUST be floating. The outputs are then connected in series with the midpoint of the two supplies forming the common ground point for the EVM. Connecting the mid-point to the earth ground reference of the power supply if present is not a requirement.
