Engineering Contradiction Analysis
1Reliability
If a complex hardware architecture is used in the adapter to handle power transmission and control, then the power transmission capability and control functionality are improved, but the component cost and device complexity increase
Solution Approach 1:
The patent combines the power transmission function and control function into a single integrated chip. The chip includes a first transmitting interface for power transmission, a second transmitting interface for control signals, and a processing circuit that integrates both functions, thereby reducing adapter hardware complexity while maintaining power transmission capability.
Solution Approach 2:
The integrated chip serves multiple functions: it transmits power through the first transmitting interface, receives and processes control commands through the second transmitting interface, generates adjustment signals, and controls the converter circuit. This multi-functionality reduces the need for separate components, lowering both complexity and cost.
2Use of energy by moving object
If separate converter circuits and control circuits are used in the adapter, then the power conversion efficiency is improved, but the component cost and circuit complexity increase
Solution Approach 1:
The patent merges the converter circuit control and power transmission control into a single integrated chip with a processing circuit. This processing circuit receives control commands, generates adjustment signals, and controls the converter circuit, thereby maintaining power conversion efficiency while reducing circuit complexity and component count.
Solution Approach 2:
The integrated chip acts as an intermediary between the converter circuit and the control system. It receives control commands through the second transmitting interface, processes them, generates adjustment signals, and controls the converter circuit, thereby simplifying the overall system architecture while maintaining efficient power conversion.
3Power
If high-voltage components are directly connected to the control circuit, then the power transmission capability is improved, but the safety and reliability decrease due to potential damage from high voltage
Solution Approach 1:
The integrated chip serves as an intermediary between the high-voltage converter circuit and the low-voltage control circuit. It includes a first transmitting interface for high-voltage power transmission and a second transmitting interface for low-voltage control signals, with a processing circuit that isolates the controller chip from direct high-voltage exposure while maintaining control capability.
Solution Approach 2:
The chip is segmented into distinct interfaces: a first transmitting interface for power transmission that can handle high voltages, and a second transmitting interface for control signals that operates at low voltages. The processing circuit is configured to receive control commands through the second interface and generate adjustment signals for the first interface, thereby protecting the control logic from high-voltage damage.

AI summary
A power transmission chip is coupled between an external converter circuit and a controller chip and includes a first transmitting interface, an internal converter circuit, a second transmitting interface, and a processing circuit. The first transmitting interface is coupled to the external converter circuit to receive a conversion voltage. The internal converter circuit processes the conversion voltage to generate an analog signal. The second transmitting interface transmits the analog signal to the controller chip and receives a control command from the controller chip. The processing circuit generates an adjustment signal based on the control command and provides the first adjustment signal to the external converter circuit via the first transmitting interface. The external converter circuit adjusts the conversion voltage based on the adjustment signal.
