摘要: A method for driving a motor by using an output stage amplifier that operates between two or more separate supply voltages, depending on the amplitude of input signal, is presented. This bridge unipolar class G allows with high accuracy and improved efficiency without introducing switching noise typical PWM driving. can be applied same benefits to AB, pseudo AB stages. When this associated imposed current approach oversampling digital analog converter resulting advantages are very significant.
