Universal Air Conditioner Control Board for Multiple Power Schemes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electric control boards for air conditioners face design complexities and increased production costs due to the need for multiple power supply schemes, leading to increased types of boards and cumbersome management.
Innovation Solution
An electric control assembly for air conditioners is designed with a modular structure including an MCU, driving circuit, switch device, rectifier circuit, wave-filtering circuit, and interchangeable power supply interfaces, allowing for connection to either a switch power supply board or a linear transformer, enabling the use of different power supply schemes without redesigning the board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different power supply schemes are applied to cope with different market environments, then the adaptability of the air conditioner is improved, but the device complexity and production management difficulty increase
Solution Approach 1:
The electric control board is designed with universal power supply interfaces that can accept both high-voltage alternating current and low-voltage power inputs. The board integrates multiple power supply schemes into a single unified design, allowing it to function with different power sources without requiring separate board designs for each market environment.
Solution Approach 2:
The power supply system is segmented into modular components: a first power supply interface for high-voltage AC input, a second power supply interface for low-voltage input, and separate mounting positions for rectifier and wave-filtering circuits. This segmentation allows flexible configuration depending on the power supply scheme used while maintaining a single standardized board design.
2Adaptability or versatility
If multiple power supply schemes are implemented, then the versatility of the air conditioner is improved, but the manufacturing workload and production management become more cumbersome
Solution Approach 1:
A single universal electric control board design accommodates multiple power supply schemes through standardized interfaces and modular circuit mounting positions. This eliminates the need to redesign boards for different power supply requirements, significantly reducing manufacturing workload and simplifying production management while maintaining versatility.
Solution Approach 2:
The board incorporates dynamic configuration capabilities where circuits can be selectively mounted or disconnected based on the required power supply scheme. The modular design allows the same physical board to be adapted to different power supply configurations without requiring separate manufacturing processes for each variant.

AI summary
An air conditioner electric control assembly and an air conditioner. The air conditioner electronic control assembly comprises an MCU (11), a drive circuit (14), a switch device (15), a rectifier circuit mounting position (12), a filter circuit mounting position (13), a first power supply interface (17), a second power supply interface (16), and a first alternating power supply input interface (18). Moreover, the connection to a switch power supply board (3) or a linear transformer (2) is implemented by the second power source interface (16) and the first alternating power supply input interface (18), so that a power supply module adapting to different power supply schemes is implemented. Therefore, when implementing dealing with the different power supply schemes, an electric control board can be universal and does not need to be redesigned, thereby simplifying the design of the electric control board, reducing the costs, and facilitating the management during the production of an air conditioner electric control assembly.
