<p>PURPOSE: To obtain a transformer-inductor device for adjusting voltage while self-controlling a reactive power by connecting the first edge part of three legs via the first common point of a core and connecting the second edge part of the three legs via the second common point of the core. CONSTITUTION: A self-adjustment-type transformer-inductor device with an air gap has a three-leg-type core 1 that is made of a central leg 2 and two outer legs 3 and 4. The upper edges of the legs 2, 3, and 4 are connected one another via the first common point of the core and the lower edges of the legs 2, 3, and 4 are connected one another via the second common point of the core 1. An AC coil winding 9a and a DC control coil winding 10a are mounted around the leg 3 and an AC coil winding 9b and a DC control coil winding 10b are mounted around the leg 4. A coil winding 16 has a first terminal that is connected to an open-type terminal of the coil winding 9a and a second terminal that is connected to an AC side output 19 of a diode bridge 11, thus obtaining a transformer-inductor device for adjusting voltage while self-controlling a reactive power.</p> |
