Abstract
There is provided a hybrid fiber coaxial network polarity switching module (60) connectable to a DC power signal obtained by rectification of an AC power signal and comprising a controller (64) in electrical communication with an H-bridge circuit (62), wherein the controller (64) is configured to act on the H-bridge circuit (62) to switch polarity of the DC power signal during a transition time less than or equal to the effective time of the AC power signal. A method of switching polarity in an HFC network is also provided.

A hybrid fiber coaxial network polarity switching module connectable to a DC power signal obtained from an AC power signal and comprising a controller in electrical communication with an H-bridge circuit, wherein the controller is configured to act on the H-bridge circuit to switch polarity of the DC power signal during a transition time less than or equal to the effective time of the AC power signal.
A method of switching polarity in an HFC network comprising passing a DC power signal obtained from an AC power signal through an H-bridge circuit and controlling the H-bridge circuit to switch polarity of the DC power signal during transition time less than or equal to the effective time of the AC power signal.
