Power Mux for low voltage AC line

Matt Alizadeh

Other Parts Discussed in Thread: TPS2120

Hi All,

I'm looking for a component, otherwise a circuit, that acts as a power mux for two 32VAC lines.

I could find TPS2120 which does similar job but multiplexes between two positive DC levels.

Is there any component or circuit to do the requested job?

regards,

Thanks

Hi Matt,

Thanks for reaching out!

We do not have products for AC line power muxing. What is the load ? Is there any DC stage before going to load ?

There will be a DC stage (rectifier, regulator, etc) in the load to run processor and LEDs however input to the load has to be 32Vac.

If not a component, any idea what minimal circuit?

Hi Matt,

One option is to use DC power muxing devices after rectifier + regulation stages.

I believe AC line power muxing needs complex voltage/frequency synchronize circuits but I have never done.
