Efficient-switching-controller


Posted on Dec 3, 2012

This high-performance switching controller for a low-power de servo motor uses a symmetrical complementary- transistor bridge. The bridge acts as a reversing switch between the motor and a single-ended power supply. Since the transistors operate either fully on or completely off, except during a very short transition period, much less heat is dissipated than in linear-amplifier circuits. Damping is provided by the circuit`s inherent dynamic braking.

Since either maximum or zero voltage is applied to the motor, the dynamic response is faster than that of linear servo drives.
