Engineering Contradiction Analysis
1Power
If DC-DC conversion circuits are used for voltage boosting or reducing, then voltage and current can be adjusted, but conduction losses and switching losses increase, resulting in high power loss
Solution Approach 1:
The patent extracts and removes the DC-DC conversion circuit from the power supply system. By eliminating this intermediate conversion stage, the system achieves direct power output from the power supply to the load, thereby removing the source of conduction and switching losses while maintaining voltage and current adjustment capabilities through alternative means
Solution Approach 2:
The patent introduces a programmable power supply as an intermediary device that directly negotiates and adjusts power parameters with the load through communication protocols. This mediator eliminates the need for traditional DC-DC conversion by enabling intelligent, direct power delivery with programmable voltage and current control

If DC-DC conversion circuits are used, then voltage boosting or reducing is achieved, but conversion loss increases
Solution Approach 1:
The patent implements dynamic power adjustment through a programmable power supply that can real-time modify voltage and current parameters based on load requirements. This dynamic control mechanism replaces static DC-DC conversion with flexible, software-controlled power delivery that adapts to changing conditions without conversion losses
Solution Approach 2:
The patent changes the fundamental parameters of power delivery by transitioning from fixed voltage/current conversion to programmable parameter control. The system can dynamically alter voltage, current, and power levels through communication protocols, enabling precise parameter adjustment without the energy losses inherent in traditional conversion circuits

AI summary
The present invention discloses an outdoor electrical system and method based on a programmable power supply, pertaining to the field of outdoor electrical appliance, wherein the programmable power supply receives a data request signal from an outdoor electrical appliance, dynamically adjusts the output voltage based on the data request data, and then outputs it to the outdoor electrical appliance; when the output power of the outdoor electrical appliance is greater than a preset threshold, the power supply output is directly output to the electrical load through a set programming and protection detection module, and when the output power is less than the preset threshold, the power supply output is adjusted through a set low power conversion module before being output to the electrical load, which achieves that the energy conversion is completed in one step within the programmable power supply, without the need for a DC-DC conversion circuit in between, effectively reducing the number of energy conversions on the power consumption side, achieving the effect of reducing energy conversion loss, and enhancing the output conversion efficiency of the outdoor electrical system.
