Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer stacked capacitor type device. Background Art

[0002] "Transformer stacking" refers to stacking multiple independent transformers together to achieve specific electrical performance and power requirements. This stacking usually involves stacking multiple magnetic coils (also called windings) together so that they share the magnetic field and achieve higher performance or a specific voltage / current conversion ratio.

[0003] Series stacking: In series stacking, the outputs of multiple transformer windings are connected together to form a single circuit path. This stacking can increase the overall voltage conversion ratio. For example, connecting two transformer windings in series can double the output voltage of a single transformer.

[0004] Parallel Stacking: In parallel stacking, the input or output of multiple transformer windings are connected to each other to form a parallel circuit path. This stacking can increase the overall current capacity or power handling capability. For example, multiple transformers connected in parallel can handle higher currents together without exceeding the limitations of a single transformer.

[0005] Hybrid stacking: Hybrid stacking combines the characteristics of series and parallel connections to achieve more complex electrical performance. By connecting and configuring transformer windings in different ways, specific requirements of various circuits can be achieved, such as voltage step-up and step-down, impedance matching, etc.

[0006] Transformer stacks are often used in applications that require customized voltage / current conversion or power conditioning, such as power systems, wireless communication equipment, industrial electronics, and power supply equipment. The design of stacked transformers needs to take into account the electrical insulation and magnetic coupling effects between the individual windings to ensure stability, efficiency, and safety.

In addition, it is not easy to operate in series stacking, parallel stacking, and mixed stacking. If the positive and negative poles are connected reversely by mistake, short-circuit components may be damaged at the least, and the equipment may explode and endanger personal safety at the worst.
