Power conversion and switching

First-order switching models and explicit nonidealities.

input/output range, load, switching frequency, ripple targets → duty, inductance, capacitance, stresses

input/output range, load, frequency, efficiency, ripple → duty, inductor current, nominal L/C

voltage range, load, topology, frequency → duty range, current and voltage stresses

input/output range, load, thermal model → loss, efficiency, temperature estimate

current waveform, Rds(on), switching times, voltage, frequency → conduction, switching and gate-drive losses

gate charge, frequency, desired switching time, voltage → driver current, gate power, resistance screening

AC input, load, diode drops, smoothing capacitance → DC range, ripple, diode dissipation

bus, load, device parameters, PWM → device currents, losses, recirculation assumptions

parasitic L/C or ring data, voltage, repetition rate → candidate R/C, dissipation estimate

applied volt-seconds, inductance, switching period → ripple, peak and RMS currents

power/current transient, bus bounds, duration, ESR → required capacitance, ripple-current demand

source impedance, capacitance, voltage, limiting method → peak current, charging time, limiting losses
