Abstract
Apparatuses, systems, and methods to balance flying capacitors in high power multi-level buck or boost converters for renewable and solar maximum power point tracking (MPPT) inverter applications are provided. An exemplary method includes initializing at least a multi-level converter circuitry and an isolated secondary converter circuitry, wherein the multi-level converter circuitry includes at least a flying capacitor, and wherein the isolated secondary converter circuitry is configured to charge the flying capacitor in accordance with a default operation state in response to initialization; determining that a voltage across the flying capacitor satisfies a threshold; and causing the isolated secondary converter circuitry to switch from the default operation state to an inactive state based at least in part on the voltage satisfying the threshold.
