1.5 volt batteries in parellel using a dc-dc boost converter ?

yes I know 1.5 as a minimum 3.7 may be more appropriate but desired result is to avoid series batter deficiency focus on capacity and leave voltage to circuitry, a chain is only as strong as its weakest link yada yada yada! use solid state rather than relays. use mosfets in parallel to handle reqired current. yes! it is true , I have a lot to learn. power could be controlled by frequency of low voltage battery bank, output as 3 phase at desired frequency cps. wel that is my thoughts and I am sure someone has worked with this idea, after all I am not the only dumb person. yes you guessed;

recharging alkaline cells with a pwm charger40-200 cpm @ 80% on 20%off use batteries in a lower draw condition e.g. d cell max 10 amps.each
