Title: Folke J Ekelund: Innovator in Power Connection Systems
Introduction
Folke J Ekelund is a notable inventor based in Norsborg, Sweden. He has made significant contributions to the field of electrical engineering, particularly in power connection systems. With a total of three patents to his name, Ekelund's work focuses on enhancing the reliability and efficiency of power systems.
Latest Patents
Ekelund's latest patents include a "System for Power Connection and Reconnection" and a "Short Circuit Limiting Protector." The power connection system introduces a full float system with Transient Free Multiple Load Disconnection Reconnection (TFMLDR). This innovative system ensures that loads and dedicated rectifiers are always connected, allowing for controlled disconnection and reconnection without producing voltage transients. This is particularly advantageous during mains power failures, as it stabilizes the DC power supply to the load.
The short circuit limiting protector utilizes an electronic and thermal feedback principle for precise and rapid release. It features a non-linear temperature-dependent resistor in the collector circuit of a field effect transistor, which acts as a current valve. This design allows for the monitoring of total current and replaces conventional fuses, providing a more efficient response to faults in the load.
