Reactor having relay member with input/output terminal
A reactor includes: an outer peripheral iron core; three leg iron cores; and three coils, each of the coils having an input side coil end and an output side coil end projecting from a same end surface on an end side in the axial direction of the three leg iron cores, where the three coils include two first coils in which a projecting position of the input side coil end and a projecting position of the output side coil end has a first relative positional relationship and include one second coil having a second relative positional relationship opposite to the first relative positional relationship and where winding directions from the input side coil end to the output side coil end of the first and the second coils are reversed to each other.
1. A reactor comprising:
an outer peripheral iron core;
three leg iron cores provided on an inner surface side of the outer peripheral iron core and spaced apart from each other in a circumferential direction; and
three coils wound around each of the three leg iron cores, each of the three coils having an input side coil end and an output side coil end projecting from a same end surface on an end side in an axial direction of the three leg iron cores;
the three coils including
two first coils in which a projecting position of the input side coil end and a projecting position of the output side coil end at a portion projecting from the end surface have a first relative positional relationship, and
one second coil in which the projecting position of the input side coil end and the projecting position of the output side coil end at the portion projecting from the end surface have a second relative positional relationship opposite to the first relative positional relationship; and
a winding direction from the input side coil end to the output side coil end of the first coil and a winding direction from the input side coil end to the output side coil end of the second coil being reversed to each other.
2. The reactor of claim 1 , further comprising;
three input terminals to which the input side coil ends of the first coils and the input side coil end of the second coil are individually connected; and
three output terminals to which the output side coil ends of the first coils and the output side coil end of the second coil are individually connected, wherein
the three input terminals and the three output terminals are arranged to gather on opposite sides to each other on the end side in the axial direction.
3. The reactor of claim 2 , further comprising:
first relay members, each of the first relay members connecting respective one of the input side coil ends to respective one of the input terminals; and
second relay members, each of the second relay members connecting respective one of the output side coil ends to respective one of the output terminals.
4. The reactor of claim 2 , wherein
each of the input side coils end is directly connected to respective one of the input terminals, and
each of the output side coils end is directly connected to respective one of the output terminals.
