How Fast Can You Build an Operating Map of a Buck Converter?
A real-SIMBA study based on the official buck converter example. Automated transient sweeps across switching frequency and load are used to build a first operating view from physically interpretable metrics such as output voltage, output ripple, average inductor current, and execution time. The article also shows how two real 1D sweeps can be turned into an estimated operating-map visualization for workflow purposes.
Dead Time vs Current in a SiC Half-Bridge: A Practical SIMBA Exploration
Dead time in a SiC half-bridge should not be copied as a fixed gate-driver constant. This article uses the official SIMBA double-pulse example to show a practical sweep workflow, extract waveform-based indicators from real transient runs, and explain how to interpret a dead-time study honestly before scaling it to more aggressive current levels.
Exploring the Operating Boundaries of a PSFB Converter with SIMBA
A phase-shifted full bridge can look healthy at nominal conditions, then drift into stressed operation as input voltage, frequency, or output inductance move. This article uses real SIMBA transient sweeps to build a practical operating-boundary map and show why Design Space Exploration matters for PSFB design.
Observing Magnetic State Variables in a Forward Converter with SIMBA
Most simulation tools treat transformer cores as fixed inductance values. This article demonstrates how SIMBA's permeance-network magnetic domain model exposes internal magnetic state variables — flux rate, winding current, and magnetic operating trajectory — directly from a Python script, on a DC-DC Forward Converter with 100 V input and dual output.
Choosing Ln and Q for an LLC Converter: Why the FHA Is Not Enough
The LLC resonant converter's design hinges on two parameters: Ln and Q. This article shows how to map the real gain curves using SIMBA and why FHA-based parameter selection can fail near the gain boundary, demonstrated on a 400V to 300-420V, 3.3 kW design.
Which Device Runs Hottest? Starting with Conduction Analysis in a 3-Phase Inverter
In a 3-phase SPWM inverter, the six switching devices do not conduct equally. This article shows how to extract the per-device duty cycle from simulation and analysis — the first step of an electro-thermal workflow in SIMBA.
Where the Losses Come From in a 48V-to-12V Inverting Buck-Boost
The inverting buck-boost topology forces the inductor to carry more current than the load requires. At high power levels, this current stress amplifies every watt of component loss. This article shows where the losses come from — and what to do about it.
From RMS Estimates to Real Waveforms: Why Engineers Simulate PWM Inverters
A nominal RMS calculation tells you the fundamental. It misses the peak current, the startup transient, and the switching ripple. This article shows what a transient simulation reveals — and why it matters for IGBT selection and thermal design.
From Nominal to Robust: Validating Power Converter Designs with Monte Carlo Analysis in SIMBA
Learn how to use Monte Carlo analysis in SIMBA to move from nominal to robust validation of power converter designs, identifying worst-case operating points across component tolerances.
