<p><P>PROBLEM TO BE SOLVED: To provide a compact reactor aggregate with small leakage inductance capable of performing soft switching in addition to a voltage step-up operation and a voltage step-down operation. <P>SOLUTION: The reactor aggregate 1A includes an annular magnetic core 10 having a pair of coil winding portions 10c arranged in parallel and an end core 10e, a main coil part 11 having a pair of main coils 11a and 11b, and a sub-coil part 12 having a pair of sub-coils 12a and 12b. One end of a winding of the main coil part 11 and one end of a winding of the sub-coil part 12 are joined. As the winding of each turn constituting the main coil 11a (11b) and the winding of each turn constituting the sub coil 12a (12b) are provided alternately one by one, the leakage inductance can be decreased. Since the magnetic core 10 is shared between the main coil part 11 and the sub-coil part 12, the reactor aggregate can be formed small in size than in the case that a resonance reactor is a separate member. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
