Environment Parameters

Set parameters that apply to all connected SPICE-compatible blocks

Libraries:
Simscape / Electrical / Utilities

Description

The Environment Parameters block lets you set parameters that apply to all SPICE-compatible blocks in an electrical network:

• Circuit temperature

• Minimum conductance

If your model does not contain an Environment Parameters block, all blocks use the default values of these parameters. To override the default values, connect every network in the system to an Environment Parameters block.

Note

The simple semiconductor models in the Semiconductors sublibrary are not temperature dependent, so the Environment Parameters block only changes the minimum conductance parameter used by the exponential diode and bipolar transistor models.

Examples

Specify Temperature on SPICE Diode Block with Environment Parameters Block

Use the Environment Parameters block to change the temperature of a SPICE Diode block in a simple circuit.
