AI Technical Summary

Technical Problem

Existing integrated transformers are difficult to dynamically adjust magnetic flux, resulting in low efficiency over a wide operating range and easy core saturation, thus limiting their applicability.

Method used

The magnetic core assembly with elastic support and magnetic flux adjustment mechanism are adopted. The air gap size is adjusted by driving the magnetic core body to move relative to the axis through a piezoelectric ceramic sheet. Combined with an oil-lubricating structure, smooth transmission and adjustment accuracy are ensured.

Benefits of technology

It achieves continuous dynamic adjustment of magnetic flux, balances the force on the magnetic core, avoids skew and jamming, ensures smooth transmission and displacement accuracy, and adapts to input voltage fluctuations and load changes.

Abstract

The invention discloses an integrated transformer with a dynamic magnetic flux adjusting function, and belongs to the technical field of transformers. The packaging shell is fixedly arranged on the substrate, and a sealed mounting cavity is defined by the packaging shell and the substrate; the magnetic core assembly is arranged in the sealed mounting cavity and comprises two magnetic core bodies which are oppositely arranged in the axial direction and an elastic supporting piece, the central areas of the two magnetic core bodies are oppositely combined to form a central magnetic column, a variable air gap is formed between the edge areas, and the elastic supporting piece is connected with the magnetic core bodies and the substrate or the packaging shell; the elastic reset device is used for enabling the magnetic core body to float in the axial direction and achieve elastic reset. The planar spiral coil is fixedly arranged on the substrate, is arranged between the internal gaps of the two magnetic core bodies, and is coaxially arranged around the central magnetic column; the magnetic flux adjusting mechanism is arranged on the peripheral side of the magnetic core assembly in a surrounding mode. According to the transformer, continuous dynamic adjustment of working magnetic flux can be achieved, the multiple sets of piezoelectric ceramic pieces which are evenly arranged in the circumferential direction enable the magnetic core body to be stressed in a balanced mode, movement is stable, and deflection and clamping stagnation of the magnetic core body are effectively avoided.
