Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a medical power supply flat panel transformer. Background Technology

[0002] With the continuous development and increasing sophistication of medical electronic equipment, extremely high demands are placed on the reliability, stability, and safety of power supplies. As a core component of medical equipment power systems, the medical power supply flat-plate transformer faces numerous technical challenges in achieving multi-output to meet the power supply needs of different medical modules.

[0003] Currently, high-frequency interference is a particularly prominent issue in multi-output medical power supply planar transformers. Medical equipment operates in complex environments, and high-frequency signals generated by internal circuits and the external electromagnetic environment can easily interfere with planar transformers, leading to output voltage fluctuations and signal distortion, thereby affecting the accuracy and stability of the medical equipment. For example, in devices such as electrocardiographs and monitors, which require extremely high precision in signal acquisition and processing, high-frequency interference may cause errors in the acquired physiological signals, leading to misdiagnosis or missed diagnosis. Simultaneously, the electromagnetic radiation generated by the planar transformer itself during high-frequency operation can also interfere with the normal operation of other medical equipment and may even pose potential health hazards to patients and medical staff.

[0004] Furthermore, high leakage inductance is also a key issue with multi-output medical power supply flat transformers. High leakage inductance reduces the transformer's energy transfer efficiency, increases power loss, causes severe overheating, and affects its lifespan and reliability. In multi-output applications, inconsistencies in leakage inductance can also lead to voltage imbalances between output branches, making it impossible to provide stable power to different modules of medical equipment and failing to meet the high precision and stability requirements of medical devices.

Additionally, the flat winding has a more concentrated magnetic field distribution, making it more prone to high-frequency radiation, while the round conductor winding has a stronger magnetic field dispersion. Alternating arrangement of these two windings can disperse the radiation sources, reducing EMI noise peaks. The inclusion of a filter magnetic ring 6 effectively suppresses high-frequency interference.

Through this arrangement, the first cable 51 can be fixed in the first positioning hole 81, and the second cable 52 can be fixed in the second positioning hole 82. Then, glue is poured into the fixing groove 8, thereby making the overall structure stable and reliable.
