Simultaneous distribution of AC and DC power
First Claim
Patent Images
1. A method for simultaneous distribution of AC and DC power, the method comprising:
- receiving a source AC power signal and chopping the source AC power signal resulting in a chopped AC power signal;
receiving a separate source DC power signal and chopping the source DC power signal resulting in a chopped DC power signal;
combining the chopped AC power signal and the chopped DC power signal resulting in a combined AC and DC power signal;
distributing the combined AC and DC power signal over a single power signal carrying medium; and
separating the combined AC and DC power signal into a first signal comprising the chopped DC power signal and a second signal comprising the chopped AC power signal.

Abstract
A system and method for the transport and distribution of both AC (alternating current) power and DC (direct current) power over wiring infrastructure normally used for distributing AC power only, for example, residential and/or commercial buildings'"'"' electrical wires is disclosed and taught. The system and method permits the combining of AC and DC power sources and the simultaneous distribution of the resulting power over the same wiring. At the utilization site a complementary device permits the separation of the DC power from the AC power and their reconstruction, for use in conventional AC-only and DC-only devices.

11. A power system comprising:
-
a DC power source configured to produce a DC power source signal; an AC power source configured to produce an AC power signal; a power combiner comprising a MUX and a PWM power switching device configured to receive the DC power source and create a chopped DC signal, receive the AC power source and create a chopped AC signal, and combine the chopped AC power signal with the chopped DC signal, resulting in a combined AC and DC power signal; a power distribution means configured to distribute the combined AC and DC power signal from the power combiner to a power utilization site; and a power separator comprising a demultiplexer at the power utilization site, wherein the power separator separates the combined AC and DC power signal into a first signal comprising the chopped AC signal and a second signal comprising the chopped DC signal; and a low-pass filter configured to receive the first signal and the second signal to produce a reconstructed output AC power signal and a reconstructed output DC power signal.
