<p>PURPOSE:To obtain a composite AC reactor in which a plurality of AC reactors and transformers are made composite, in which the number of components is reduced and which is made lightweight. CONSTITUTION:A composite AC reactor 70 which is composed of a common- mode choke coil and a power choke coil is formed of a rack-shaped core which is provided with magnetic legs 73, 73 and with outside magnetic legs 75, 76, in which the legs are brought into close contact with each other in a faced state so as to have gaps G1, G2 and in which windings NA, NB have been conducted to the magnetic legs 73, 74. In addition, a standby transformer which is formed of an E-shaped core 41 which is provided with a central magnetic leg 42, with magnetic legs 44, 45 and with outside magnetic legs 46, 47 additionally at their outside and in which windings N1, N2 have been conducted to the central magnetic leg 42 is plane-coupled to the composite AC reactor 70. At this time, a gap G2 is conducted to the tip of the central magnetic leg 42. In the same manner, a composite AC reactor which is formed of a power choke coil and of a standby transformer is formed.</p> |
