Title:
FILTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/033710
Kind Code:
A1
Abstract:
A filter device (10) is electrically connected between a power conversion device (2) and a power supply (1), said power conversion device (2) including a converter unit (3) for rectifying an input and an inverter unit (4) for inversely converting the output of the converter unit (3). The filter device (10) is configured by housing a filter reactor (11) for removing harmonic components and a boost reactor (12) for raising the voltage of the current passing through the filter reactor (11) in a filter main body (20). In the boost reactor (12), a coil (12b) is wound while appropriately interposing spacers (123) between an iron core (12a) and the coil (12b) to form an air ventilation path (125) between the inner and outer circumference portions of the coil (12b). The boost reactor (12) is housed so that air passing through the ventilation path (125) passes around the filter reactor (11) disposed in a region directly above the boost reactor (12).
