I know how boost converters work but reading your great explanation made me realize how similar they are to an impact wrench. Ever wonder how an impact wrench creates such massive torque?
Spin up a fly wheel then let it hit the dogs greatly amplifying the torque through stored kinetic energy similar to an inductor being dumped.

I always like how electricity can be compared to mechanical and hydraulic systems, it's not always perfect but there is obviously a lot of overlap between voltage, current, pressure, flow, torque and rpm. Power is the common thread.
- onjectic 4y agoWell it actually is physically equivalent considering: speed * torque = power = voltage * current. Switching voltage regulators are just gearboxes for electricity. Maybe you could even say LDOs are kind of like brakes on a car, since they throw away energy as heat to regulate speed.
- SigmundA 4y agoI don't agree, transformers are more like gears, while switching boost converters are more like impact wrenches. LDO's as brake yes I see that. However the analogy is never perfect even if useful.
