An AC power factor conditioning circuit consists of a circuit with AC power lines (12, 14) each having a path to neutral. A first path (36) from line (12) has a choke (28) coupled in series with a capacitor (38). The second path (48) has a second choke (30) coupled in series to a capacitor (50). The choke (28) includes a first coil portion (32) wrapped around a ferromagnetic core (26), and a portion of second path (48) while the second coil portion (34) is wrapped around a portion of the second path (48). The second choke (30) has a similar arrangement The chokes (28, 30) connected to power lines (12, 14) act to balance inductive loads e.g. those caused by heavy motors and fluorescent lights. Transient suppressors such as varistors (18, 20, 22, 24, 56, 58) are used for transient suppression.
