1. A method of powering an alternating current (AC) load with a power source, the method comprising:
flowing, by the power source, a direct current from an energy storage device of the power source to the alternating current (AC) load along an electrical path;
periodically, by the power source, disconnecting and re-connecting the direct current from the electrical path to generate a rectangular wave form; and
in response to the rectangular wave form being generated, powering the alternating current (AC) load with the energy storage device,
wherein the periodically disconnecting and re-connecting the direct current from the electrical path is at a frequency between 95 Hz and 130 Hz, and
wherein a duty cycle of the periodically disconnecting and re-connecting the direct current from the electrical path is between 80% and 98%.
