1. A module-based energy system, comprising:
a converter-source module, comprising:
a first energy source;
an energy buffer connected to an output of the first energy source; and
a converter coupled with the first energy source by a connection to an output of the energy buffer, wherein the converter comprises a plurality of switches configured to select an output voltage of the module; and
a local control device communicatively coupled with the converter-source module, wherein the local control device is configured to generate a plurality of switching signals for the plurality of switches,
wherein the local control device is configured to:
receive a reference signal and a modulation index from a master control device;
modulate or scale the reference signal using the modulation index; and
use the modulated or scaled reference signal for generation of the plurality of switching signals;
wherein the local control device comprises a balancing controller, wherein the balancing controller comprises:
a peak detector circuit configured to detect a peak value of the reference signal; and
a divider circuit configured to generate a normalized reference signal by dividing the reference signal by the peak value of the reference signal, wherein the balancing controller is configured to modulate scale the normalized reference signal by the modulation index to produce the modulated or scaled reference signal.
