Power electronics demand robust protection. IPM module protection offers built-in safeguards, while discrete solutions rely on external components. Which is better for your application? This article compares both approaches, highlighting:
✔ Key differences in design
✔ Performance trade-offs
✔ Best-use scenarios
What is IPM Module Protection?
An intelligent power module integrates:
Power switches (IGBTs/MOSFETs)
Gate drivers
IPM module protection features:
Overcurrent shutdown
Thermal monitoring
Undervoltage lockout
This self-contained design simplifies system architecture.
Discrete Protection Solutions
Traditional setups use:
Separate power devices
External protection ICs
Additional PCB space
Common safeguards include:
Fuses
Current sensors
Temperature probes
