Abstract
A power conditioner for AC power lines has a choke and capacitor coupled in series across the power lines. The choke comprises a coil terminating in a line, with the line looped back through the coil. The power lines are thereby balanced to provide greater operating efficiency. Capacitors and transient suppressors (e.g., varistors) are used for transient suppression and power factor correction.
Claims23
A power conditioner for AC power lines comprising:
- a first path containing a first choke in series with a capacitor;
- a second path containing a second choke in series with a capacitor;
- means for coupling said first path from a first line of an AC power source to a neutral of said source;
- and
- means for coupling said second path from a second line of said source to said neutral;
- wherein said first choke comprises a coil with a winding around said second path;
- and
- said second choke comprises a coil with a winding around said first path.
A power conditioner for AC power lines comprising:
- means for coupling to a neutral, a first line, a second line and a third line of a three phase AC power source;
- a first choke in series connection with a capacitor to provide a first path from said line to said neutral;
- a second choke in series connections with a capacitor to provide a second path from said second line to said neutral;
- said first choke comprising a coil with a winding around said second path;
- said second choke comprising a coil with a winding around said first path;
- a third choke in series connection with a capacitor to provide a fourth path from said second line to said neutral;
- a fourth choke in series connection with a capacitor to provide a fourth path from said second line to said neutral;
- said third choke comprising a coil with a winding around said fourth path;
- and
- said fourth choke comprising a coil with a winding around said third path.
A power conditioner for AC power lines comprising:
- a choke;
- a capacitor;
- and
- means for coupling said choke and capacitor in series across an AC power source;
- wherein said choke comprises a coil terminating in a line, and said line loops back through said coil.
A power conditioner for AC power lines comprising:
- a first path containing a first choke in series with a capacitor;
- a second path containing a second choke in series with a capacitor;
- means for coupling said first path across an AC power source and
- means for coupling said second path across said AC power source;
- wherein said first choke comprises a coil with a winding around said second path;
- and
- said second choke comprises a coil with a winding around said first path.
A choke for use in an AC power conditioning circuit comprising:
- a first coil terminating in a first line;
- and
- a second coil terminating in a second line;
- wherein said first line passes through said second coil and said second line passes through said first coil.
