Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional uninterruptible power supply system is used, then power supply continuity is maintained, but the system complexity and cost increase significantly
Solution Approach 1:
The power supply system is divided into multiple independent power input modules (first power input module, second power input module, etc.), each with its own non-return valve module. This segmentation allows the system to maintain simplicity while providing redundancy and continuity through modular architecture.
Solution Approach 2:
Non-return valve modules are introduced as intermediary components between power input modules and the active pulse wave generation unit. These intermediaries enable automatic power source switching without requiring complex control circuits, thereby maintaining reliability while reducing overall system complexity.
2Reliability
If multiple power input modules are used, then power supply stability is improved, but the control complexity increases
Solution Approach 1:
The non-return valve modules provide automatic power source selection and switching functionality without requiring external control signals. The system serves itself by using the inherent properties of non-return valves to detect power quality and automatically switch between power sources, eliminating the need for complex control logic.
Solution Approach 2:
The control unit continuously monitors the operating states of multiple power input modules through detection circuits and automatically adjusts the switching of non-return valve modules based on real-time power quality assessment. This feedback mechanism ensures stable power supply while maintaining simple control architecture.
3Reliability
If a hold-up time circuit is implemented, then power continuity during transitions is ensured, but the device complexity increases
Solution Approach 1:
The hold-up time circuit is pre-configured within the DC power processing unit to maintain output voltage during power source transitions. By preparing the energy storage elements in advance and designing the circuit with inherent hold-up capability, the system ensures continuous power delivery without requiring complex real-time control mechanisms.

Implementation Method 1
the active pulse wave generation unit makes a positive half-cycle and a negative half-cycle of a power signal received by the input end in turned into a half-cycle in the same direction, and then continuously outputs a pulse signal
Implementation Method 2
The DC power processing unit includes a hold-up time circuit, and the hold-up time circuit provides a voltage during a hold-up time to maintain an output of the DC power signal
Implementation Method 3
the first non-return valve module being from an on state to an off state to prevent a power signal of the second power input module from flowing into the first power input module

AI summary
An intelligent stable power supply system includes a first power input module, a first non-return valve module, an active pulse wave generation unit, a DC power processing unit, and a control unit. When the control unit determines that a first voltage value is less than a first predetermined value or greater than a second predetermined value, and a second voltage value is between the first predetermined value and the second predetermined value, the control unit firstly controls the first non-return valve module being from an on state to an off state, and then controls the second non-return valve module being from an off state to an on state so that a power signal of the second power input module flows into the active pulse wave generation unit and the DC power processing unit to output a DC power signal.
