In my application Battery is connected to load through Mosfet, and the mosfet is switched continously, wat i observe is the battery voltage drops from 3V to 2V in 7 hrs,
But when i coonect the battery with load with mosfet continuously on , the battery voltage doesnt drops much. So whether switching is creating any impact on battery voltage
Switching a mosfet on and off costs energy. Especially when you switch at high frequencies.
You have to charge and discharge the gate, which causes losses per cycle.
There are high speed technics to lower these losses. I thought one was resonant switching technic. (for power supplies)
