A new solver called BDSED is added. This solver is more efficient in solving stiff circuits that have small time constants (for example, due to parasitic inductances in the range of nH and parasitic capacitances in the range of pF).
Physical IGBT and SiC MOSFET devices used in DSIM simulation are now defined in a device database. The Device Database Editor can be used to conveniently add a new device or manage existing devices.
Power loss calculation
In addition to the switching transients, the conduction and switching losses, as well as the junction temperature, of physical IGBT and SiC MOSFET devices can be calculated.
Previously only switch converter modules were supported. Now, discrete (single) diode, IGBT, and SiC MOSFET switches can be used to build arbitrary converter circuits.
A synchronous machine model with external excitation is added.
New power elements
Several power elements are supported, including coupled inductors and transformers.
New control elements
Several control elements are supported, including integrators, filters, PID block, and ZOH block.
Several voltage and current sources are supported.
For the DSIM only version, the graphic user interface of the schematic editor and the waveform display program are improved with simpler and more modern look.
Link to DSIM
DSIM is a new simulation engine for large-scale power converter systems. With a groundbreaking simulation algorithm and modeling approach, DSIM achieves an unprecedented and unparalleled performance.
DSIM is seamlessly integrated into the PSIM simulation environment. It is available as a cost-added option by itself or in combination with the PSIM engine.
