1 New Features in PSIM Version 10.0 Highlights of key new features in PSIM version 10.0: Diode model with reverse recovery MOSFET model with turn on/turn off transient New and faster multisine ac sweep method Inductor winding and core loss calculation New supercapacitor model and solar cell models PWM IC models Multi level modeling Project function for schematic file and documentati ion management Multi language support Description of key new features in Version 10.0, as compared to Version 9.3, is given below. Diode and MOSFET Models with Switching Transient A diode model with reverse recovery is provided. This model simulatess the diode turn off process, and helps to predict switching phenomena caused by the diode reversee recovery. In addition, a MOSFET model with turn on/turn n off switching transientt is provided. With this model, one can simulate the switching transient and design the gate drive circuit. The figure below showss the simulated waveforms of a diode and MOSFET. MOSFET voltage and current Diode current Page 1

2 New Multisine AC Sweep Method A new ac sweep method based on the multisine algorithm is provided. In most cases, this method gives faster results than the previous ac sweep method. Inductor Winding and Core Loss Calculation The functionn to calculate inductor winding and core losses is added to the Thermal Module. Based on the core type and size, core material, and winding selection, this function can calculate the winding and core losses, as well as core temperature rise. This function gives a very quick and convenient way of estimating magnetics losses. Together with the other functions in the Thermal Module, one can estimate the overall efficiency of a power converter system. Inductor core and bobbin Inductor wire New Supercapacitor Model and Solar Cell Models based on the EN50530 Standardd A supercapacitor model is added to the Renewable Energyy Module. This model simulates the charging and discharging process of a supercapacitor. It also takes into account multiple cells in series and in parallel automatically. In addition, two solar cell models for crystalline silicon and thin film, based on the European Standard EN50530, are added. The EN50530 Standard provides a standard procedure for testing photovoltaic inverters. These two models provide a way to model the solar generator. IC Models A list of PWM IC, driver IC, and other IC models are added to the standard PSIM Element library, making it very easy to simulate switchmode power supplies. The following IC models are included: PWM ICs UC3823, UC3825, UC3842/ /3843, UC3844/3845, UC3846, UC3854, UC3872, UCC3806, UCC3817/3818, UCC3895 MOSFET drivers IR21834, IRS21867, TC4423A/4424A/4425A/4426A/4427A/4428A 555 timer Page 2

3 Level 1 New Features in PSIM Version 10.0 Multi Level Modeling A multi level modeling concept is introduced in v10. This is based on the need thatt different levels of models are needed at different stages of the simulation. Multi level models are provided for resistor, inductor, capacitor, diode, MOSFET, and PWM ICs. One cann easily change from one level of the model to another with just the change of a flag without changing the schematic, greatly facilitating the simulation process. The figure below, for example, shows the Level 1 and Level 2 models of an inductor. Level 2 Other Key New Features and Improvements Project Functionn for File Management The project function is provided. This function allows uses to organize and manage a project with all the schematic files, graphs, and documents, all in one easily accessible environment. This function also makes it very easy to create a different study with changes in the schematic or parameters, and compare with the original study. For example, the figure on the right shows a projectt of a power factor correction circuit based on UC3854. The original study is UC3854_PFC, and a variation of the studyy is created as UC3854 Rev1. The schematic files and the graphs of each study are listed. The UC3854 datasheet is also listed as part of the project. Page 3

4 Improved Network License Managemen nt In this version, the numbers of network users for PSIM and add on Modules can be individually managed. For example, one can have a network license with 5 users for PSIM, 3 users for Motor Drive Module, and 2 users for Digital Control Module. This flexibility allows one to tailor the network license to one s exact need. Parameter Sweep with Multiple Variables Previously, only selected parameters can be swept and only one parameterr can be swept. In v10, any parameters can be swept and multiple parameters can be swept at the same time. Improved Design Suite Interface The interface of the Motor Control Design Suite and HEV Design Suite is improved. Now the input parameterr dialog of the Design Suite is embedded with the schematicc itself, and by changing input parameters, the parameter file is updated directly. Printing Size Selection The function to select worksheet size is added. This allows the schematic to be printed properly on a variety of paper sizes. Embedded Waveform in Schematic A simulation waveform can be embedded in a schematic. This allows users to display key waveforms together with the schematic, making it easier for visual inspection and documentation. The figure below shows an active filter circuit with the load current and source current waveforms displayed. External Parameters in C/DLL Blocks In this version, it is possible to define a parameter inn a parameter file, and use this parameter inside a C block or DLL block directly. This makes it easier to bring a variable value into the C/DLL block, and make the coding easier. Page 4

5 Editing Multiple Elements The function to select multiple elements of the same type and edit their parameters at the same time is provided. This greatly speeds up circuit editing. Multi Language Support This version has the capability to support multiple languages. Page 5
