Blocks - By Category

The Power System Blockset main library, powerlib, organizes its blocks into libraries according to their behavior. The powerlib window displays the block library icons and names. This section contains the block library hierarchy and the block library contents, a listing of all Power System Blockset blocks arranged by library.

Use the Simulink Library Browser or the Power System Blockset library to access the blocks directly, guided by this hierarchical library list.

• The Electrical Sources library contains blocks that generate electric signals.
• The Elements library contains linear and nonlinear network elements.
• The Power Electronics library contains power electronics devices.
• The Machines library contains machinery models.
• The Connectors library contains blocks that can be used to interconnect blocks in various situations.
• The Measurements library contains blocks for the current and voltage measurements.
• The Extras library contains three-phase blocks and specialized measurements and control blocks. This library can also be opened by entering powerlib_extras in the MATLAB window.
• The Demos library contains useful demos and case studies.
• The powerlib window also contains the Powergui block that opens a graphical user interface for the steady-state analysis of electrical circuits.

The Simulink models of the nonlinear blocks of powerlib are stored in a library named powerlib_models. These Simulink models are used by the Power System Blockset to build the equivalent Simulink model of your circuit. See the Advanced Topics chapter for a description of the powerlib_models library.

The subsequent pages contain reference information for all blocks in Power System Blockset, arranged in alphabetical order by block name.
