1Duration of action of stationary object
If a converter operates for a long time, then power conversion function is maintained, but heat is generated by electronic elements reducing performance and durability
Solution Approach 1:
The converter is divided into two separate printed circuit boards (first PCB and second PCB) that can be independently managed. The first PCB contains heat-generating elements while the second PCB contains control elements. This segmentation allows independent thermal management of each board, enabling the heat-generating components to be replaced or cooled without affecting the entire converter assembly.
Solution Approach 2:
Heat-generating electronic elements are extracted from the main control circuitry and placed on a separate first printed circuit board. This extraction allows the heat source to be physically separated from sensitive control components, enabling targeted heat dissipation strategies and component replacement without disrupting the entire system.
2Ease of manufacture
If the converter uses an integrated structure, then manufacturing is simplified, but replacement of heat-generating components requires altering the entire module
Solution Approach 1:
The converter architecture is segmented into modular printed circuit boards connected via connectors. The first PCB containing heat-generating elements can be independently removed and replaced by disconnecting connectors, without requiring modification of the second PCB or the entire converter housing. This modular design simplifies repair operations while maintaining manufacturing efficiency.
Solution Approach 2:
The converter design incorporates detachable connectors that enable dynamic reconfiguration and replacement of printed circuit boards. This dynamic interface allows the first PCB to be easily swapped out for maintenance or upgrading of heat-generating components, transforming a previously static integrated structure into a maintainable modular system.
