Great article with a host of practical circuit suggestions. I can see using this approach on a handheld battery-based instrument used in the field. A solar charging option is a perfect feature when you can't get back to 'base camp'.

It's a simple, elegant approach covered by quite a few papers. If it has a downside, it's that you do need to _know_ what the "maximum power voltage" parameter is for your panel. Maybe this can be acquired in production line calibration. Solar panels are rather variable from batch to batch, so you can't just fit and forget this sort of electronics to an arbitrary panel. The extra complexity of a routine that goes looking for the maximum power point does reduce this concern. but for 'emergency' operation, the last few percentage points of conversion efficiency aren't your main concern.

NEXT UPCOMING BROADCAST

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.
