How this tool works
Eleven guided modules cover regulator efficiency, ideal converter relationships, magnetic ripple, semiconductor losses, thermal design, and full power budgets.
All plots label voltage, current, time, power, temperature, duty cycle, and efficiency units explicitly.
Numerical inputs, imported state, text lists, and graph samples are bounded before calculation and rendering.
Core equations
D≈Vout/VinΔIL=VL·D/(Lf)Pcond=I²RDS(on)DPsw≈½VI(tr+tf)fTj=Ta+PΣθη=Pout/PinAssumptions
- Converters operate in idealized steady state unless a ripple waveform is shown.
- Efficiency is entered as a lumped assumption in converter modules.
- Flyback calculations use a simplified discontinuous energy-transfer model.
Limitations
- Not a substitute for magnetic core design, control-loop compensation, switch-node ringing analysis, isolation safety, creepage/clearance review, EMI testing, device SOA verification, PCB layout analysis, or regulatory compliance.
