Power Electronics Engineer Circuit Simulation PCB Design
Welcome! I am a Hardware Engineer expert in power electronics, circuit simulation, and PCB design. I help startups, engineers, and product developers build efficient SMPS, DC DC converters, motor driv...
Informazioni su questo servizio
Is your power converter blowing up MOSFETs? Experiencing unexpected voltage spikes, feedback loop instability, or high switching noise? Don't waste money fabricating broken PCBssimulate and debug first!
I provide professional circuit simulation, troubleshooting, and optimization using LTspice, PLECS, and MATLAB/Simulink.
What I Can Help You With;
Transient & Steady State Analysis; Verify switching performance, duty cycle, and voltage/current stresses.
Troubleshooting & Optimization; Fix MOSFET/IGBT failure points, ringing, and EMI noise spikes.
Control Loop Stability; Bode plots, gain/phase margin analysis, and feedback compensation tuning.
Component Sizing; Inductor/transformer core sizing, switching frequency tuning, and filter design.
What You Will Get;
Fully functional, verified .asc or .plecs simulation source files.
High resolution waveform plots (Voltage, Current, Power Dissipation).
Clear engineering explanation on why the issue occurred and how it was resolved.
Save time and fabrication costs. Send me your circuit details or existing simulation file to get started!

FAQ
What files will I receive upon completion of the simulation gig?
You will receive the fully runnable .asc source file (for LTspice) or .plecs / .slx model, all custom component .lib or .sub files used, high-resolution annotated waveform plots, and an engineering summary explaining the results.
Can you import custom SPICE models from manufacturers like TI, Infineon, or Wolfspeed?
Yes. If your circuit uses specific MOSFETs, GaN FETs, IGBTs, or PWM controller ICs not available in the default LTspice library, I will locate, import, and configure the vendor's third-party SPICE models into t
Why is my physical circuit blowing up MOSFETs when the theoretical math looks right?
Theoretical equations ignore non-ideal parameters like stray PCB inductance, MOSFET gate ringing, parasitic capacitance, and core saturation. I simulate these parasitic dynamics in LTspice to identify exact failu
Can you perform control loop stability analysis (Bode Plots)?
Yes! I run AC sweep simulations to plot open-loop and closed-loop frequency responses, measuring Gain Margin and Phase Margin to tune Type II or Type III feedback compensation networks for switching power supplies.
What if I don't have a simulation file yet and only have a paper circuit diagram?
No problem. Send me your paper diagram or schematic PDF, and I will build the complete LTspice model from scratch, set up the transient parameters, and run the diagnostic tests for you.
