A full-wave rectifier with a freewheeling diode is commonly used in DC motor drives to convert AC to DC and ensure smooth operation of the motor. The full-wave bridge rectifier (using four diodes) provides continuous pulsating DC to the motor, while the freewheeling diode allows the motor current to continue flowing during the intervals when the AC voltage crosses zero. This is essential for inductive loads like DC motors, as it prevents sudden voltage spikes, reduces torque ripple, and improves overall performance. The setup enhances reliability and protects the rectifier components from reverse voltage caused by the motor's back EMF.
