PWM is the duty-cycle changing. The frequency might also change but it does not need to change. Changing the frequency without changing the duty-cycle is not PWM.
I don't know what is high side and low side PWM. An h-bridge has a high side and a low side.
I don't know what is PSOC. The letters could be anything.
thnks....
psoc(program system on chip) is a product of cypress semiconductors which has a microcontroller together with many other evices like adc , comparators, sensors ,...
what is the difference with/without variable frequency???
hi,
so , if i hav to run a dc motor of certain voltage , say 12v , i can take analog voltage which averages to 12volt , connect it to a pwm and the output may b connected to the motor....will it work????
eliminators available in the market does the same thing...do they work on same principle???
With a 12V supply and a 12V motor then 100% duty-cycle from PWM will result in full power. But the PWM circuit might have some loss.
50% duty-cycle will result in almost half power but good torque.
10% duty cycle will result in low power and not bad torque.
