Power electronics design and simulation for engineers who need it to work the first time.
Reference designs get you started, not to production. The right topology emerges from honest trade-off analysis — efficiency curves, control behavior across duty cycle extremes, and how GaN or SiC actually changes the equation for your application. We work through that analysis in simulation before a single component is ordered.
Most transformer and inductor problems are design problems, not winding problems — misunderstood leakage inductance, underestimated AC winding loss, or a turns ratio assumption that doesn't hold at load. On the PCB side, EMI failures and power integrity problems rarely surface in schematic review; they live in the layout. We address both before fabrication, not after a failed chamber visit.
Circuit simulation won't tell you your transformer is going to thermally run away, or that your winding geometry is generating proximity losses that triple your copper loss at frequency. We run coupled EM, thermal, structural, and CFD analysis — because the failures that destroy hardware don't respect domain boundaries.
The bench will find what simulation missed — but only if you know what to measure and how to measure it. Ripple probing has bandwidth limits. Switch-node waveforms mislead. Control-loop stability problems surface as EMI, jitter, and load-transient failures that look unrelated. We correlate simulation to hardware and use worst-case analysis to find failures that a single prototype won't expose.
