Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single output branch provides DC power to multiple load circuits, then the power supply circuit structure is simple, but when one load circuit draws excessive current, the DC voltage signal is pulled down and affects other load circuits, reducing reliability
Solution Approach 1:
The power supply circuit is segmented into multiple independent output branches, each serving specific load circuits. The power assigning elements further divide each output branch into multiple power assigning units that can independently control power distribution to different load circuits, preventing interference between loads
2Adaptability or versatility
If the output power of the power supply circuit is fixed, then the circuit design is simple, but it cannot adapt to varying load requirements, reducing power efficiency
Solution Approach 1:
The power assigning elements dynamically adjust the power distribution to each load circuit based on actual power requirements. The control signals generated by the power assigning elements vary the power allocation in real-time, allowing the fixed output power to be efficiently distributed according to varying load demands
Solution Approach 2:
The power assigning elements change the power parameters (voltage, current) delivered to each load circuit by adjusting control signals. This allows dynamic modification of power delivery characteristics without changing the overall output power capacity of the supply circuit
