Description

Staggered reverse coupling Boost-buck reactor

Technical Field

The utility model relates to an alternating expression reverse coupling Boost-buck reactor.

Background

As shown in fig. 1, the structural schematic diagram of a built-in reactor of a single-phase (single-inductance) Boost-buck electric vehicle between a conventional rated operating current of 30 to 250A is shown, and the built-in reactor of the single-phase (single-inductance) Boost-buck electric vehicle between the conventional rated operating current of 30 to 250A is composed of a winding 11, a framework 12, a first amorphous iron core 13, a second amorphous iron core 14, an air gap plate 15 and a stainless steel strip 16.
