US Patent:

20080025053, Jan 31, 2008

Filed:

Jul 25, 2007

Appl. No.:

11/881169

Inventors:

Michael Januszewski - Downers Grove IL, US

International Classification:

H02M 1/12

US Classification:

363039000

Abstract:

A power supply system with transient suppression includes an uninterruptible power supply (UPS). A power conditioning circuit is coupled to the UPS for conditioning power supplied by a power source at a nominal frequency over line, neutral, and ground conductors, respectively. The power conditioning circuit includes first, second, and third inductors coupled in series between the line, neutral, and ground conductors, respectively, and the first, second, and third power conditioning circuit output lines, respectively. All of the power supplied by the power source to the first, second, and third output lines flows through the first, second, and third inductors. Each of the inductors blocks power at frequencies greater than the nominal frequency from reaching the first, second, and third output lines.

International Classification:

H03H 7/00

US Classification:

333184

Abstract:

A power conditioning circuit for conditioning power supplied by a power source at a nominal frequency over conductors in a polyphase system includes first and second phase conductors. First and second inductors are connected in series between the first and second phase conductors and first and second phase output lines, wherein all of the power supplied by the power source to the first and second phase output lines flows through the first and second inductors. An inductance of each of the first and second inductors increases when power at frequencies greater than the nominal frequency flows through the first and second phase conductors, thereby blocking power at frequencies greater than the nominal frequency from reaching the first and second phase output lines.

Abstract:

The disclosed embodiments relate to method and/or device which is effective at cancelling or altering electrical signals or pulses, generated by, for example, digital electronic systems and components, that are induced, reflected or otherwise made present on the mains power supply conductors and/or the earthing or grounding conductor (if present.) The disclosed embodiments cancel these electrical signals thereby providing an effective means of preventing the exfiltration of various data from a computing or similar system by means of power line emissions. The disclosed embodiments may perform this subjugation by: altering the shape of the fundamental current and voltage waveforms and also altering and diminishing any non-fundamental frequency waveforms to a point where they are no longer measurable or detectable; and preventing the communication via inductive coupling of any electrical signals on mains current onto the grounding path or vice versa.
