Don't most switching voltage regulators (except the low-current switched cap variety) already use inductors/transformers as the main energy storage element between the rails? Don't the capacitors mainly filter switching and ripple currents?
Using inductors to store energy for digital circuits sounds challenging. Digital circuits require currents in spikes at the switching instants and inductors are not the ideal tool for this. The Ldi/dt drop in inductors will cause additional voltage drops and may not be suitable for digital circuits.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
