The article mentions 8/20 surge pulses as 8ms/20ms. That's wrong. The time scale is in microseconds. A pulse of 8kV with 20ms decay is a *very* large energy. TVSes are capable of absorbing power up to 400~5000W, depending on the model, but a 20ms pulse would require a much larger device.
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.
