4 Conclusion

Using the same process any low voltage (<=36 V), low frequency (<=60 Hz), AC supply can be modified to support a shared data and power bus by using a filtering capacitor on all power nodes. This will create the condition in which the THVD80x0 devices assumes to be true – the inductors are AC grounded – with this filtering capacitor the inductors are essentially AC grounded as the voltage will be attenuated by the inductors not over the power source or load. Once this filtering capacitor is added the design process is the same as one would use for DC power systems.
