Latest Patents
One of Satterfield's latest patents involves reducing a drop in a residual supply signal level during the startup or restart of a power supply. In this embodiment, a power-supply controller is designed with a control circuit, a drive circuit, and a signal-drop-reducing circuit. The control circuit generates a drive signal with a specific duty cycle, while the drive circuit enables a phase circuit of the power supply to produce an output signal of a certain magnitude. The signal-drop-reducing circuit plays a crucial role by disabling the driver circuit when the duty cycle corresponds to a signal magnitude that is lower than the output signal's magnitude. This innovation effectively minimizes the drop in the residual output signal that can occur when restarting the power supply.
Another patent by Satterfield outlines a method for generating a pulse-width-modulated signal with a duty cycle. This method isolates a power-supply output node based on the duty cycle, particularly when the signal magnitude is less than the output signal's magnitude. This technique is particularly useful for power supplies that maintain a non-zero residual output signal after deactivation, allowing for a smoother restart process.
