Spice

PSIM, an industry standard for system-level and control simulation, is excellent for simulations which require a longer simulation time to understand their full impacts. SPICE excels in device simulation, which allows for the study of things like parasitic interactions and gate drive with short simulations.

With a vast library of SPICE models for industrial devices, SPICE provides the ability to analyze a particular device in detail, for example, the turn-on and turn-off transient of a semiconductor device.

Added in PSIM version 11.1 is the ability to make use of the LTspice* engine to run models.

The SPICE Module provides access to:

• Dual PSIM/SPICE model definitions
• Running LTspice from PSIM
• Import of existing SPICE libraries and subcircuits
• Non-linear Capacitor model
• AC sweep of switchmode circuit in SPICE

The integration of SPICE into PSIM allows users to greatly reduce development time as a simulation does not need to be re-made in a new environment to study device level interactions.

We anticipate that users will use PSIM to study:

• Topology verification
• Control loop and stability
• Steady-state junction temperatures and other thermal simulations
• Component sizing such as energy storage devices
• Code generation

Once the designer has an understanding of their converter it is then appropriate to dive down to a device level simulation by swapping ideal switches for SPICE models. Swapping to SPICE models will allow the designer to study:

• Gate drive requirements
• Switching and conduction losses
• Parasitic interactions
• Switch transition stresses

The combination of PSIM & SPICE provides the ultimate environment for all your design needs.
