can you explain the basic reason why boost converters seem to be more popular than voltage doubler circuits for load bearing output.

I have built these 2 circuits in the simulator and they both basically achieve the same result of charging an 80v battery from a 48v supply.

I have built the boost converter on a circuit board and wasted many hours blowing up MOSFETs and making the circuit work on a real world circuit board with reasonable success.

I have also built a voltage doubler circuit that achieves producing the desired voltage output but only when not under any real load. yet in the simulator it works as well as the boost converter.

what are practicality / lifespan / cost reasons why boost converters are used for high current voltage doubling. is there any point in me persevering with making my voltage doubler circuit work properly.

It is all a learning curve really but it would be nice to be able to actually charge my 80v battery at the end of it.

so far i can charge the battery at 1 amp with my home made boost converter as long as i remember to unplug the input power before the output power, it blows the MOSFET if i disconnect the output while its running, but i think that's a microcontroller issue not responding to the rise in voltage fast enough when the load is disconnected and the PWM duty becomes to high, that i should be able to overcome if i think about it.
