AI Technical Summary

Benefits of technology

This patented solution allows flexDC electronics manufacturers to test their equipment more efficiently while still ensuring they are safe against damage caused due to external factors like weathering (rain) water spray). Additionally, it simplifies the process of simulating an AC power supply with various types of electrical loads such as motors and generators without requiring any specialized training. Overall, these improvements improve efficiency and safety measures over existing methods.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving flexibility in controlling and protective power distribution networks that use multiple types of electrical equipment such as electricity meters or sensors connected through wires. These devices can be subjected to different operating environments with varying levels of stress due to factors like temperature changes over time (temperature drift). Additionally, these sources may have variations in impedance values caused by aging components inside them themselves. Existing methods based on simulation only provide limited accuracy when applied at realistic times because they require frequent maintenance checks after production has been completed.
