התרחיש
A 60V switch-mode power supply drives a DC motor. During regenerative braking, the motor can generate back EMF that exceeds the supply rail, risking damage to the SMPS and downstream electronics.
מה מופיע בתרשים הזה
פענחו את ההחלטות שמאחוריו.
01
Add a flyback diode across the motor to clamp inductive kickback
02
Place a TVS diode across V+ and V- to absorb regenerative overvoltage
03
Include a fuse and run switch for overcurrent protection and manual control
Use when protecting an SMPS-powered DC motor drive from back EMF and voltage transients during braking or freewheeling.
