Simba is a modeling and simulation software for power electronics engineers. With an intuitive and sleek interface, it helps engineers to analyze and design complex systems such as power supplies, motor drives or grid-connected converters.
SIMBA includes component libraries in different domains: electrical, mechanical, thermal and control. The electrical library includes components such as inductors, capacitors and power semiconductors switches, the mechanical library includes electrical motors, inertia and friction element, etc.
Lightning Fast Power Electronics Solver
SIMBA proposes a new type of transient solver with a predictive time step which adapts to the different discontinuity events and time constants of the circuit. Thus, it offers an incredible performance and accuracy.
Graphical User Interface
SIMBA offers a sleek graphical user interface which does not need any training so that users are immediately operational.
Real time scope
Results can be visualized in scopes during and after simulation. It provides classical features to zoom, analyze waveforms and to extract measurement data (instantaneous, average and rms values, FFT calculations, etc).
Automatic Steady-State detection
SIMBA can find the steady state operation of the simulated electrical circuit. It is especially useful during a parametric analysis because each run can have different time constants and the Stop at Steady-State feature ensures that each run will stop at its steady state.
With this AC sweep feature, SIMBA allows the user to determine open-loops and control-loops transfer functions of power switching converters on a user-defined frequency range.
SIMBA control library proposes a C-code block which allows the user to directly write C-code and to build its own control model blocks. The C-code is compiled (and not interpreted) with GCC 64 bits when the simulation starts which allows the user to include his own header or to debug his code.
Thermal management of power semiconductors switches is a key issue to design power converters with higher density and higher efficiency. SIMBA allows the user to consider together thermal and electrical simulations of the power converter operation. It takes into account switching and conduction losses from the commutated current and voltage recorded during the simulation and from look-up tables of switching energies and voltage drops depending on current, voltage and temperature values.
Sensitivity analysis is a key step to analyze a power system operation. SIMBA proposes a parametric sweep which helps the user to automate a single parameter variation and the corresponding simulations.
SIMBA modeling, simulation and analyses steps can be run from python scripts. This gives to the user incredible degrees of freedom towards analysis and design automation of power converters. See python library page for more details.
