DC-Link Voltage Measurement

Pin 14 and pin 26 of connector JP1 provide access to the DC-link voltage. Three possible feedback cases are

associated with this pin. Figure 19 provides the DC bus sense resistor details. By default, the resistor R14 is not

mounted on Eval-M3-TS6-665PN. There must be a pull-down resistor mounted on the corresponding controller

board.

Figure 19

DC bus sense resistor on Eval-M3-TS6-665PN evaluation board

If a pull down resistor of 13.3 kΩ referred to ground is inserted either on the Eval-M3-TS6-665PN evaluation

board or on the control board, the DCBSense voltage results in the range of 0 to 3.3 V on the pin reflecting a DC

bus voltage range of 0 to 420 V.If a pull down resistor of 13.3 kΩ is inserted on both, Eval-M3- TS6-665PN

evaluation board and on the control card, the DCBSense results scale to 0-1.65 V. No safety issue occurs. If no

feedback is desired on the DCBSense pin, R2 or R7 should be removed to avoid high voltage on the connector.

The high side resistors R2 and R7 for the DC bus sensing resistor divider on the controller board EVAL-M3- TS6-

665PN are 2000k

and should be configured in MCEWizard as shown in Figure 20. For the low side resistor

value, please refer to the User Manual of the corresponding control board.
