Utilities

Faults, environmental parameters

Blocks in the Utilities library allow you to model time- and event-based faults and to set parameters for multiple SPICE-compatible blocks.

Simscape Blocks

Environment Parameters	Set parameters that apply to all connected SPICE-compatible blocks
Fault	Electrical fault with temporal, behavioral, or external trigger
Fault (Three-Phase)	Signal-enabled or time-based, single-phase, two-phase, or three-phase, grounded or ungrounded fault

MOSFET Fault in Buck Converter

How a fault may be applied to a MOSFET in a power converter in order to explore the operation of protection circuitry. After the MOSFET becomes faulted, the crowbar circuitry is activated in order to clamp the output voltage across the load and eventually to cause the fuse to blow.
