Problems solved by technology
At present, the transformer and the inductor are two separate electrical devices with a large volume. When different frequency conversion power supplies are required, different inductors need to be replaced. If the inductance is too small during replacement, the effect of suppressing harmonics is not ideal, and the inductance is too large , can not meet the requirements of transient current tracking, the operation is troublesome, time-consuming and labor-intensive

A transformer with adjustable leakage inductance, comprising a transformer core, a primary winding of a transformer, a secondary winding of a transformer, an additional iron core and an additional winding. The core is inserted into the sliding groove of the above-mentioned transformer core, the transformer core and the additional core form a whole, and the secondary winding of the transformer on the transformer core and the additional winding of the transformer on the additional core are connected in series to form a leakage current The secondary winding of the adjustable inductance transformer. Its structure is simple, the transformer and inductor are integrated, it is convenient to adjust the frequency conversion power supply to match the inductor, and the volume of equipment and the amount of debugging and maintenance are reduced.
Description
technical field [0001] The invention relates to a transformer, in particular to a transformer with adjustable leakage inductance suitable for the field of electrotechnical technology. Background technique [0002] With the development of power electronics technology and computer technology, frequency conversion power supply is widely used in electric drive, wind power generation, solar power generation and other fields. In the variable frequency power supply, a transformer is generally required to convert the voltage level to meet the requirements of the variable frequency power supply voltage level. At the same time, an inductor is needed to balance the voltage, support reactive power, store energy and suppress harmonic current. At present, the transformer and the inductor are two separate electrical devices with a large volume. When different frequency conversion power supplies are required, different inductors need to be replaced. If the inductance is too small during rep...
