1Object-affected harmful factors
If an EMI shielding layer is used to transmit power signals, then electromagnetic interference protection is improved, but power loss increases
Solution Approach 1:
The EMI shielding layer is divided into multiple segments with different functions: a first shielding layer for transmitting power signals and a second shielding layer for receiving regulated voltage. This segmentation allows each layer to be optimized for its specific function, reducing overall power loss while maintaining EMI protection.
Solution Approach 2:
A voltage regulator is introduced as an intermediary component between the power source and electronic components. The regulator is positioned adjacent to the EMI shielding layer and converts the unregulated voltage from the first shielding layer into regulated voltage for the second shielding layer, reducing power loss while maintaining shielding effectiveness.
2Loss of energy
If a voltage regulator is added to regulate voltage from the EMI shielding layer, then power loss is reduced, but device complexity increases
Solution Approach 1:
The voltage regulator is merged with the EMI shielding structure by positioning it adjacent to the first EMI shielding layer and integrating it into the overall device architecture. This combining approach allows the regulator to perform its voltage regulation function while occupying minimal additional space and maintaining a compact device structure.
Solution Approach 2:
The first EMI shielding layer serves multiple functions: it provides electromagnetic interference protection and simultaneously transmits unregulated voltage to the voltage regulator. This multi-functionality reduces the need for separate dedicated voltage transmission paths, thereby reducing overall device complexity despite adding the regulator.
