AI Technical Summary

Benefits of technology

This patented innovative design allows for better control over electronic components connected together without increasing their size. It achieves these technical benefits by connecting multiple different parts (such as transistors) within an insulator called a combination busbar, allowing them to connect directly instead of being tied up at one end like traditional connections. Additionally, there're no longer any metal conducting paths around those points where they may get bent during normal operations. Overall, this new technology improves the performance and efficiency of electric chargers while reducing unwanted side effects such as noise induction from nearby metals.

Problems solved by technology

Technological Problem: Current converters use multiple parts such as transformer cabinets, power controllers, insulation systems, etc., making them difficult to install due to their complexity. Additionally, these units require separate connections between different elements like cathode ray tubes, secondary batteries, and ground busbars, increasing the risk of failure modes caused by external factors like vibrations and impact loads.
