Servo motor drive amplifier


Posted on Feb 4, 2014

Digital ICs and opto-isolators provide the drive for this TMOS servo amplifier, resulting in fewer analog circuits and less drift. Fast and consistent turn-on and turn-off characteristics also enable accurate analog output results directly from the digital signal without the need for analog feedback.An `H` bridge configuration is employed for the servo amplifier,which obtains complementary PWM inputs from digital control circuits.The PWM inputs are applied via opto-isolators
