DC-Link Voltage Sensing

The DC-link voltage (V

DC

) is sensed on the secondary side of the driver board between the DC plus and DC

minus terminal. After digitizing and transmitting the measured value to the primary side via a galvanic
isolation, the digital value is converted back to an analogue signal on the primary side. The analogue DC-
link voltage signal is available on the SKiFace interface (see Table 5—1) with the characteristic given in
Table 5—10.
