Simulation Cases
DSIM simulation engine employs the discrete state algorithm in the event-driven mode, which takes full advantage of the characteristics of power electronic systems and achieves fast simulation speed, especially in large-scale or high-frequency systems. Compared to other existing simulation tools, DSIM can typically achieve a hundred-fold simulation acceleration under the same level of accuracy. Several simulation examples demostrate the performance comparison with other simulation software.
Discrete state algorithm is essentially a variable step algorithm, which realizes adaptive numerical integration of the system state with minimal computation. Event-driven method eliminates unnecessary iterative calculation caused by frequent switching events in power electronic systems. Due to the variable step size algorithm, the user does not need to choose the appropriate step size. The DSIM simulation engine will adaptively select the step size in each calculation step. The following figure illustrates the comparison between DSIM simulation framework and the traditional framework.

200kHz LLC Converter
this case, an LLC isolated bidirectional DC-DC converter with a switching frequency of about 200kHz and 8 switching devices is simulated. The 0.1-second simulation using DSIM takes no more than 1 second. Compared with the long-time simulation of traditional simulation tools at very small steps, DSIM can improve the simulation speed by more than 1300 times.

50kVA solid state transformer
this case, a low-voltage ride-through simulation is performed on a 50kVA three-stage solid-state transformer (SST). The switching devices use the ideal switching model and the transient switching model respectively. When the switching device uses the transient switching model, the 5-second simulation using DSIM takes no more than 50 seconds. DSIM can increase the simulation speed by more than 700 times on the premise of ensuring the simulation accuracy.
