Nor does it make sense to measure the efficiency of a boost converter as a single, static number. In the real world, that'll depend on 1) the input and output v

Nor does it make sense to measure the efficiency of a boost converter as a single, static number. In the real world, that'll depend on 1) the input and output voltages, 2) the load, 3) the switching frequency, and 4) the parameters of the inductor (like its resistance and saturation current). (A big missing piece here is regulation - all of the test circuits are running open-loop with a 1 kHz square wave switching waveform. Real switching regulators observe the voltage at the output and adjust the switching duty cycle and/or frequency to hit the target voltage.)
