情境
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.
這張圖裡有什麼
看懂背後的決策。
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.
