inductor-switching-audit-cites-every-source - Electronic Circuits XIII & XIV: Power Supplies and Switching Energy Step by Step

An inductor-switching-audit-cites-every-source scan requires the final accepted bit to trace back through ramp, energy, work, volt-second balance, buck average, and power checks. The 0 V*s balance, 3 V output, 6 W load power, and 1/2 A average input current are exact only for the stated ideal source chain. Real switching converters add ripple, parasitics, switch loss, diode drops, ESR, control timing, thermal limits, calibration limits, and measurement uncertainty.

The capstone accepts one coherent switching-energy ledger. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

The capstone audit has to cite every upstream source

The final accepted value is downstream of ramp, energy, work, balance, buck-average, and power checks.

\text{audit}=\text{ramp}+\text{energy}+\text{work}+\text{balance}+\text{buck}+\text{power}

The source chain stays accepted as load current changes

Each row rebuilds the full source chain. The load current changes power, but every accepted bit remains source-bound.

\begin{array}{c|c|c|c}I_{\text{out}}&P_{\text{out}}&I_{\text{in(avg)}}&\text{gate}\\1\ \text{A}&3\ \text{W}&\tfrac{1}{4}\ \text{A}&\text{pass}\\2\ \text{A}&6\ \text{W}&\tfrac{1}{2}\ \text{A}&\text{pass}\\3\ \text{A}&9\ \text{W}&\tfrac{3}{4}\ \text{A}&\text{pass}\\\end{array}

The switching converter audit cites every accepted source

The final accepted bit is not a caption: it follows the ramp, energy, work, balance, buck, and power source refs.

0\ \text{V}\cdot\text{s};\quad V_{\text{out}}=3\ \text{V};\quad P_{\text{out}}=6\ \text{W};\quad I_{\text{in(avg)}}=\tfrac{1}{2}\ \text{A}
