Hi...
Recently I made a PWM circuit to drive A Strip of LED.
The Circuit consists LM324N and drive a mosfet at 200Khz.
As I know that to calculate efficiency of a device I need to calculate the input power and the output power. Ef = (Output Power/ Input Power)*100.
But in my case in put power is 6V x 1A = 6W and what about the output power? as It's provide pwm signal in different duty cycle controlled by the pot?
What is the best way to calculate the output power?
I used the circuit provided in the below link. Changed the capacitor and resistor to get the desired frequency.
