A high-frequency transformer is ≥€α∏a device that converts al$↓α‍ternating current into high-frequency alteσ‍"™rnating current, con∞★sisting of two parts: an i♦< πron core and a winding. The winding is w∏£ ound on the iron core, and the φ✘ ↔magnetic core in the winding is maβ©gnetized. By utilizing ₹∞the change in inductance, high-f∏Ω ®requency alternating current can be≈≥ converted into low-frequency sinusoid↔£al alternating current.

High frequency trans"€'₹former is a device t₩φ×≥hat converts high-freqπ™δ→uency alternating current and playσ©→¥s an important role in powe ₹‌‍r electronic devices. It converts DC voltage i®αnto AC voltage with extremely high frequ>φency, low frequency, and hig₹&h power, thereby achievinλ∑g energy conversion and transmis↕₽φsion.

High frequency transformers can be d♠ βivided into two types:•↓↕ DC transformers and AC×₽₹™ transformers. The winding of an AC ☆€transformer consists of seveπ★←ral iron cores connected in series o Ω↕✘r parallel, which are filled witπ∑h insulation material to&€ε★ make them proportio$''¥nal to the power supply  ™voltage. The iron core of an ₹★®δAC transformer is co¶₹§mposed of an insulation layerλ↕δ↓ and enameled wire, which can be used as an e₹∞lectrical connection device and has charac±‌teristics that DC transformers do not posσ≤ sess. For example, both passive and ↑∑active methods can be used as high-frπ✘÷equency power sources. In additi£¶₹δon, the magnetic core of high-frequency ≥₹$αtransformers can be large orφ∑∑δ small, and the coil can also be thick or thin. ₩​ Structurally, high-freqφ♣↔₩uency transformers can be ♣δdivided into two types: ordinar↓ ∏εy windings and special windings.

Ordinary windings are made by winding ♣± ≈a coil around a magnetic coπ&&re as the center; Special winding is forme​'§≤d by winding one or more ma∞πgnetic cores around ‌ £the iron core as the center. In practical applic<•₹♥ations, the two are often used in combination. Hi<±gh frequency transformers usu☆×∏←ally use special windings to meet the high-fre ₽®quency performance requirements in ↔™specific situations.

High frequency transformers are✔← composed of iron cores, windings, an φ∞d insulation materials. After →↑filling the iron core∞ ↑σ with insulating material, its magnetic peε♥rmeability sharply decrea♥©ses, resulting in magnetic loss. When the op±∑erating frequency of the magne±∏tic core used in the high-frequency power s₽Ω↓upply is high, this loss is even gre✘ ater. Therefore, in order toε• minimize the losses of high-frequency ​αφtransformers, the operating fre→ ↔quency of the iron core should be∑₽← kept as low as possibl♦∏ ×e; In order to enable the insulation material to σεdissipate heat, its thick ✔ness should be appropriately increased.
