Figure 17: Typical Voltage Measurement Characteristic
If using the proposed single-ended configuration for the end-user application, it is strongly recommended to add a capacitor
parallel to resistor R29 (compare with Figure 16) in the final design to attenuate high-frequency spikes. The DC bus voltage
measurement circuit is presented in Figure 18 outlined in yellow. The DC bus voltage must be connected to the dedicated
pads on the PCB (marked with the amber color in Figure 18).
The DC bus voltage measurement circuit is placed on the detachable part of the PCB and can serve as the stand-alone
isolated DC voltage measurement board. If the DC bus voltage board is used as the stand-alone unit, the board must be
supplied with the 5V external power supply. The power supply input and measurement signal can be accessed via dedicated
pads (J5) on the PCB.
