Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe different types of Snubber circuits are given below:
1. Unpolarized series R-C snubbers: Used to protect diodes and thyristors
2. Polarized R-C snubbers:
- Used as turn-off snubbers to shape the turn-off switching trajectory of controlled switches
- Used as overvoltage snubbers to clamp voltages applied to controlled switches to safe values
- Limit dv/dt during device turn-off
3. Polarized L-R snubbers:
- Used as turn-on snubbers to shape the turn-on switching trajectory of controlled switches.
- Limit di/dt during device turn-on
