AC power conditioning circuit

A power conditioner for AC power lines comprising:

• a multi-coil choke;
• at least one capacitor;
• and
• means for coupling said choke and at least one capacitor in series across an AC power source;
• said choke comprising:
• a magnetic core structure having a first leg, a second leg and a third leg, said legs being substantially parallel to each other, the magnetic core structure being in the form of two E-shaped core components facing each other to form two magnetic cores, a first magnetic core being formed between the first leg and the second leg and a second magnetic core being formed between the second leg and the third leg;
• a first coil wrapped around said first leg;
• a second coil wrapped around said second leg;
• a third coil wrapped around said third leg;
• a fourth coil wrapped around a lead portion of said third coil but not being wrapped around the core;
• a fifth coil wrapped around a lead portion of said first coil but not being wrapped around the core;
• wherein:
• said first leg includes a first air gap, the first coil extending over and completely across the first air gap;
• said second leg includes a second air gap, the second coil extending over and completely across the second air gap;
• said third leg includes a third air gap, the third coil extending over and completely across the third air gap;
• and
• the first, second and third air gaps completely separate the two E-shaped core components.
