High Efficiency Lamp Driver Back EMF Version.

Here I show you the concept:

In response to criticism over some of my reactive circuits, I have put together a working demonstration that shows how we can achieve the same results through alternative methods. The key is to limit the current to its lowest necessary value to save on energy usage. The previous x-reactance method was just one approach among many.

In this demonstration, I use a low voltage square wave generator that operates at around 5 volts to trigger a base resistor of an NPN transistor. The transistor switches a 9-volt battery into a home-built 1.9 ohm air core coil, quickly wound with telephone cable of about 300 feet. We use diodes Bedini-style to feed the high voltage back EMF and quickly charge a 10uF capacitor to 100 volts with very little current. The sharp low 10% duty cycle holds back much of the current from leaving the 9-volt battery while producing loads of back EMF for quick charging and discharging of the 10uF capacitor at 100 volts, thanks to the SCR neon capacitor dump. We store this charge into a set of 12-volt supercapacitors, giving us steady DC in return, enough to run a small high-frequency inverter and drive the lamp at full lumens, which normally requires 15 watts at 60 hertz AC.

This circuit is more complicated, but it proves the concept further. It shows what can be done with very little current if utilized correctly. It's clear that this little 9-volt battery cannot produce "15" watts on its own without the help of additional systems such as pulsing, electrets, supercaps, high frequency, etc., thanks to running the circuit mostly as an open loop.
