Solution Overview
Problem
Existing power conversion apparatuses consume unnecessary power as they continue to provide DC power even when not connected to electronic devices or when devices are turned off, due to their passive nature and inability to adjust output power based on the state of the connected equipment.
Innovation Solution
A power conversion apparatus that uses an external signal from the electronic device to dynamically turn on or off, incorporating an AC to DC adapter, power conversion control unit, and restart circuit to manage power consumption by determining the state of the device and adjusting power output accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power conversion apparatus is connected to AC power supply, then stable DC power can be provided to electronic apparatus, but the power conversion apparatus continues to consume power even when not connected to or when the electronic apparatus is in off mode
Solution Approach 1:
The power conversion apparatus transitions from a static, always-on design to a dynamic design that can switch between on and off states. The control unit dynamically adjusts the operating state based on real-time detection of electronic apparatus status, enabling the system to adapt its power consumption characteristics to actual usage conditions while maintaining reliable power supply when needed.
Solution Approach 2:
The system implements feedback control by detecting the state of the electronic apparatus (through connection status and power consumption state) and using this information to control the power conversion apparatus operation. The control unit receives feedback signals indicating whether the electronic apparatus is connected and whether it is in on or off mode, then adjusts the power conversion apparatus state accordingly, creating a closed-loop control system that eliminates unnecessary power consumption.
2Ease of manufacture
If the power conversion apparatus is designed as a passive apparatus, then simple structure and ease of manufacture are achieved, but the apparatus cannot adjust output power according to the state of the connected electronic apparatus
Solution Approach 1:
The power conversion apparatus performs self-service by autonomously detecting the state of the connected electronic apparatus and automatically adjusting its own operation state without requiring manual intervention or complex external control systems. The control unit monitors connection status and power consumption states, then self-regulates the power conversion process, enabling the system to adapt to different usage scenarios while maintaining a relatively simple overall structure.

AI summary
A power conversion apparatus is provided. The power conversion apparatus includes an AC to DC adapter, an input port, a power conversion control unit, and a restart circuit. The AC to DC adapter converts an AC input voltage into a DC output voltage according to an external signal of an electronic apparatus and provides the DC output voltage to the electronic apparatus. The input port receives the AC input voltage through an AC input terminal. If the power conversion apparatus does not output the DC output voltage to the electronic apparatus, the power conversion control unit turns off the power conversion apparatus. If the restart circuit detects that an insertion action occurs on the input port, the restart circuit transmits a trigger signal to turn on the power conversion control unit in an off mode.
