Regulated Switching Power Supplies

In stepper and servo systems, frequent speed and torque changes result in frequent current changes drawing from power supplies. When accelerating, servo / stepper drives draw high current and requires quick response for the power supplies. In de-acceleration, stepper / servo motors generates EMF charge back voltage back to servo / stepper drives, which will require the power supplies to “absorb” such voltage to the damage of connected stepper / servo drives.
