There is no extra power , only lower power dissipated in your cell because your switching device is now acting as a resistor .
It has to do with the way you are pulsing is total crap .
Do a google search for a purpously made "mosfet driver" , then buy a power mofset .
Make sure the mosfet driver is compatible with your pulsing logic level .
Make sure to keep the leads very short , and put a bypass capacitor , as shown in the datasheet of the mosfet driver .
Dankie,
I see that i didnt wrote well down on whats happening here, so i modified the first post for better understanding.
Please read my first post and data again.
Reference =strait dc. No transistors are used there. Amps in are 0.50
With the circuit, there are still 0.50 amps flowing thru my cell.
However, input power is 28% lower.
If my cell saw a higher resistance, amps would drop and to compensate that, you must raise voltage and totall wattage.
In my case i see the totall wattage go down and still having same voltage and amps on my cell.....
Dankie, i have fets here and fet drivers. For sure i do know how to build me a nice switching circuit. Results here have nothing to do with choice of transistor or Fet or IGBT.
