摘要: Embodiments can include systems, methods, and apparatus for driving servo actuators. In one embodiment, a system may H-bridge circuit coupled to winding of the actuator, including switching devices. The controller providing control pulse width modulation (PWM) signal switches. PWM drives switches periodically establish one-direction electric current path through circuit. feedback loop configured measure flowing and, based at least in part on detection, generate frequency (PFM) signal. switch that forces operated open PFM controlling
