New Description: [New Technology Field] This creation is about a high-power transformer, especially a transformer used in a full-bridge phase-shift 1L-structure DC converter (L stands for Inductor). [Prior Art] The magnetic component is the design core of the power supply. In the design of AC/DC power supply suppliers, it is a challenge for R&D personnel to meet the high utilization of wattage and high efficiency, as well as space utilization, material selection and design costs. In the design of a small power supply with a typical output power of less than 500 watts, the main power transformer with isolation function is mostly used on the primary side (high voltage, low current side) or secondary side (low voltage, high current side). The structure of the copper wire winding. In the high-power power supply with output power greater than 5 watts, the primary side (high voltage, low current side) of the main power transformer will remain.

However, the transformer of the high-power power supply on the secondary side (low-voltage, high-current side) adopts the structure of copper wire winding, which can reduce the steel loss, _ in the face of higher wattage (output power is greater than 1〇〇〇) When the design of watts is higher, the output current is higher, so even if the original design/area design is used, the impedance will increase. The problem of increasing the phase J will reappear. M436918 In addition, the industry's most commonly used high-power AC/DC power supply Γ architecture mainly includes .LLc half-bridge resonant architecture and full-bridge phase-shift architecture. The full-bridge phase-shift architecture is divided into a 2L architecture and a 1L architecture due to the difference in the number of output inductors and the connection method. In the foregoing, L represents the inductance (|nduct〇r)' C represents a capacitance (Capacit〇r). Referring to the circuit diagram of the full bridge phase shift ratio architecture shown in FIG. 5, the full bridge phase shift 1L architecture has a main transformer Tm and an output inductor Lo, and the secondary side output of the main transformer Tm adopts a center tap design. Connected to the output inductor Lo. Since most of the industry adopts PQ type core as the core of the main transformer Tm of the full bridge phase shift 1L architecture, the ring core is used as the core of the full bridge phase shift 1 L architecture, and the inductance of the inductor L〇, and because Only the copper wire winding can be used on the toroidal core. Therefore, in order to connect the main transformer Tm to the output inductor, the secondary side of the main transformer Tm can only use the steel wire winding. That is to say, under the full-bridge phase-shifting 1L architecture, the secondary side and the human side of the main transformer Tm use the structure of the copper wire winding, so the ratio of the copper loss of the line is therefore high. Since the main transformer Tm and the output inductor are two independent components, the distance between the two is inevitably spaced during the assembly, and the distance between the segments is unequal, which in turn causes additional line loss. If it is hard to make the secondary side of the main transformer Tm and the copper wire winding in the output inductor L〇 to be wound around a copper wire without division, the difficulty of winding the process will be increased. The length of the copper wire is also difficult to control, which will make the main transformer Tm to the output inductor L. The parameter characteristics are difficult to control, and the worst case will cause the power supply's electronics to be in mass production. [New content] M436918 In view of the problems of the prior art mentioned above, the purpose of the present invention is mainly to provide a high-power transformer whose secondary side adopts a copper wire wound structure and can be applied to a full-bridge phase shift 1L architecture.

In order to achieve the above-mentioned creative purpose, the technical means utilized in the present invention is to make a transformer comprising: a second iron core, a magnetic shaft protruding from each of the iron cores, and the ends of the magnetic shafts of the two iron cores are correspondingly connected;
