Comparing Voltage Boosting Circuits
Overview & disclaimers This post compares the power efficiency of some voltage boosting circuits. The circuits discussed here are: Buck converter Parallel buck converter Serial buck converter P…
1KΩ is a representative resistance when driving CMOS logic, but too high for more complex circuits or even electric motors or larger LED installations. Parallel boost converterI “discovered” the next circuit by accident – I didn’t find any description on the interwebs, but I won’t go as far as claiming authorship. Admittedly I don’t understand every detail of its operation, my intuition is that the “kickback” from the first coil is used to feed the second BC and build up an even higher voltage there.
