Title:
REACTOR
Document Type and Number:
WIPO Patent Application WO/2011/158631
Kind Code:
A1
Abstract:
Disclosed is a reactor (1A) comprising a coil (10) formed by winding a wire, and a magnetic core (20) forming a closed magnetic circuit by means of two cores, namely an inner core (21) inserted into the aforementioned coil (10) and a connecting core (23) which is connected to the end of said inner core (21) and which covers the outer circumference of said coil (10). Between the coil (10) and the inner core (21) is provided an intermediate core (25), and by fulfilling 0B2 and B1>B3, with B1 the saturation flux density of the inner core (21), B2 the saturation flux density of the connecting core (23), and B3 the saturation flux density of the intermediate core (25), the disclosed reactor can be miniaturized while reducing loss.
