1. A method of generating power for a load using a modular battery system that comprises converter modules arranged in a plurality of cascades, wherein each cascade comprises a plurality of converter modules, wherein the plurality of cascades together output AC voltage signals of multiple phases, and wherein each converter module comprises a battery and a plurality of switches controllable to selectively output voltages from the converter module, the method comprising:
sensing operating parameters about the batteries of the converter modules, the operating parameters comprising temperatures of the batteries of the converter modules;
generating, for each cascade, respective pulse width modulated (PWM) switching signals based at least on the operating parameters about the batteries; and
controlling the plurality of switches of the plurality of converter modules of each cascade with the respective PWM switching signals such that each cascade outputs a single phase AC voltage signal comprising a superposition of output voltages from each of the plurality of converter modules of the cascade;
wherein control of the plurality of switches of the plurality of converter modules of each cascade with the respective PWM switching signals balances a temperature of at least two batteries of the plurality of converter modules.
