PowerSmart Solar Speeder, V2


Posted on Dec 15, 2012

This must be the most efficient bipolar transistor motor driver design for this application and I recommend it for the solar roller competitions. A 1381E is used to trigger at 2.4V. While it takes a total of 10 components plus motor compared to the stock circuit`s 6 components, you will clearly get better performance compared to a stock Solar Roller/Speeder circuit.

There are no losses during charging and the output transistor has a guaranteed low voltage drop under all motor load conditions while the normally wasted base current is absolutely minimized. To demonstrate the difference in wasted base current, measure t
