PSIM has gone deep into power electronics and created modules to help you with any design you can dream up (from power electronics to HEV system for example). 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.
PSIM’s SPICE Module, provides the capability to run SPICE simulation in the PSIM environment.
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.
The integration of a SPICE engine into PSIM allows for 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.
The combination of PSIM and SPICE provides the ultimate environment for all your design needs.
The picture above shows a DC-DC converter with MOSFET in SPICE model.
Thanks to the SPICE Directive Block, the user can implement very quickly the netlist of MOSFET as SPICE model.
In reallity, Functions are provided such that SPICE netlists from other SPICE software can be easily imported and simulated in PSIM.
With the PSIM engine and SPICE engine in one integrated environment, users will be able to switch easily between running PSIM simulation and SPICE simulation.
Such a combination gives users the capability to have the proof of concept quickly in PSIM, and then zoom in to study a circuit in detail in SPICE
Digital Control Module
The digital control module allows to validate a control algorithm for digital implementation
PSIM’s Digital Control module is a flexible, time-saving solution to analyze systems in z-domain and convert from analog to digital control.
To facilitate digital controller design, a utility tool is provided to convert an analog controller to a digital controller. After the controller is designed in analog s-domain taking into account the digital delay, the controller can be converted to a digital controller in z-domain and implemented directly in PSIM.
PSIM’s Digital Control Module lets you implement the digital control algorithm with z-domain simulation blocks making it easy to check the performance and stability of a digital control loop. You can easily test the effects of quantization and observe the effects of digital delay on a control algorithm, allowing users to debug and troubleshoot in a simulation environment.
For example : microcontrollers/DSPs are increasingly used in converter control in power supply and motor drive applications, requiring control algorithms to be implemented in the discrete time z-domain.
Renewable Energy Module
This module lets you simulate and analyze real-world renewable energy systems. It simplifies and speeds up the development process – without sacrificing high-quality, trusted results.
Renewable Energy module offers a range of models for solar, wind and battery storage systems, all designed to enable you to simulate, model and analyze quickly and accurately.
PSIM provides two types of PV models.
· Wind Turbine Models
The wind turbine model can simulate wind power systems as below :
Few examples in PSIM are provided and allow to have excellent starting point for custom wind power system design and analysis.
· Battery Model
In any renewable energy power system, battery storage is an essential part of the system.
PSIM’s battery model allows users to simulate battery charging and discharging process in an energy storage system. The battery model can be used to model various types of batteries.
· Ultracapacitor Model
The ultracapacitor model provides an accurate representation of the charging, discharging, and hold characteristics of an ultracapacitor. Additionally, there is an added modeling utility for extracting the parameters from the manufacturers’ datasheet (see below).
PSIM’s Thermal module lets you quickly estimate power loss calculations and compare multiple conditions and devices.
The Thermal module provides a very quick way of estimating conduction and switching losses of semiconductor devices (diode, IGBT, MOSFET) but also core and winding losses for inductors.
One important tool is the « Device database editor » :
The Device Database Editor (PcdEditor) provides a convenient way to add new devices and manage existing devices. These devices can then be used in the PSIM schematic and their power losses calculated in the simulation. In addition, utility tools are provided to capture device characteristics curves directly from device datasheet images.
One major advantage of the Thermal module is that the loss calculation is done in such a way that it does not slow down the simulation. The loss calculations are thermally dependent and the junction temperature or core temperature is used by the models to reflect this dependence.
User can compare different operating conditions, or comparing devices of different manufacturers.
The software PSIM is developed by Powersim and exclusively distributed by Powersys in Europe and Israel.
PSIM is a simulation environment for power conversion and control that will allow your group to gain a competitive edge.
With PSIM’s powerful simulation environment, it will allow you to work more efficiently, reducing the development cost and time-to-market. It is one of the fastest simulators for power electronics simulation. It achieves fast simulation while retaining excellent simulation accuracy. This makes it particularly efficient in simulating converter systems of any size, and performing multiple-cycle simulation. There are many optional add-on Modules available to address specific needs in various applications. These Modules give you the flexibility to tailor PSIM for your own needs, and significantly enhance PSIM’s capability.
