Insulated Signal Transmission Module With Series Transformers

The transformer is divided into two separate transformers connected in series, with each transformer having its own independent insulation structure. This segmentation allows the primary and secondary circuits to be isolated more effectively, reducing noise and inductance while maintaining high dielectric breakdown voltage through the combined insulation effect of both transformers.

An insulation plate is introduced as an intermediary element between the primary and secondary circuits. This insulation plate acts as a mediator that provides electrical isolation without requiring direct transformer coupling, thereby reducing the inductance and noise associated with traditional transformer designs while maintaining the necessary dielectric breakdown voltage.

The insulation structure uses composite materials combining multiple insulation layers and the insulation plate. This composite approach provides high dielectric breakdown voltage through the synergistic effect of different insulation materials, achieving the required electrical insulation without requiring excessive thickness of any single material, thus minimizing device size.

The insulation design transitions from a single-dimensional thickness approach to a multi-dimensional structure involving stacked insulation layers and the insulation plate positioned between primary and secondary circuits. This dimensional approach distributes the insulation function across multiple layers and spatial arrangements, achieving high dielectric breakdown voltage without proportionally increasing overall device volume.
