Dear Sir/Madam, Presently I am doing a project on wheelchair which use a 24V DC motor to drive it. I would like to implement the use of pulse width modulation to control the speed of the motor. However, at my very best knowledge, all the PWM circuit that I saw is low input voltage which range from 5 to 12V. Hence do you have or know a PWM circuit with an input of 24V? Your suggestions or comments are welcome. Regards, Zhongyang Biomedical Engineering Ngee Ann Polytechnic
