Hello All,
I am trying to determine if it is possible to develop a constant power load circuit using microcontrollers. Is it possible to use the PWM feature on a microcontroller to control the power being delivered from a battery load? The microcontroller would use two A/D converters one for voltage and another for the current and then calculate the power. The PWM output would adjust its duty cycle depending on if the calculated power is lower or higher than the set value. Is this possible? How are constant power loads normally made using digital and analog circuits? I have uploaded a circuit of what I am thinking.
