PWM/linear driver for an electromagnetic load |
摘要 |
The present invention relates a Pulse Width Modulation (PWM)/linear driver for an electromagnetic load by a bridge circuit of the type having a signal input and a signal output and at least two conduction control inputs for driving a voice coil motor in a linear mode and in a pulse width modulation. The bridge circuit is driven by a PWM converter coupled to one of said two control inputs and by a linear amplifier coupled to the other of said two control inputs.
