Latest Patents

Fenton's latest patents include a "Transformer Coupled Power Switching Circuit" and a "Motor Control System for a Single Phase Induction Motor." The transformer coupled power switching circuit is designed to switch power repetitively to a load at a relatively low frequency. It employs a power switching device driven across an isolating transformer interface, utilizing high-frequency pulse signals modulated with low-frequency switching information. This design allows for isolated driving with fast switching edges while requiring only a small transformer. The detection circuit derives power through the rectification of high-frequency signals induced in the transformer secondary.

The motor control system for a single-phase induction motor utilizes power line-assisted starting and operates at a frequency higher than the power line frequency from an electronically generated inverter supply. This innovative system provides an out-of-phase mains frequency signal to the run winding during starting, creating the necessary rotating magnetic field. Once the motor has started, the power line supply is disconnected from the start winding, and the inverter supply frequency is gradually increased to achieve the desired operating speed. Notably, this system eliminates the need for phase-shifting capacitors, optimizing the run winding for efficient operation.
