  • Patent number: 12328080
    Abstract: Provided are embodiments for a system and method for controlling a boost control circuit. Embodiments include a power supply and a boost converter circuit coupled to the power supply, wherein the boost converter circuit is operable to provide power to the load. Embodiments also include a 3-phase inverter coupled to the boost converter, wherein the 3-phase-inverter is operable to provide a 3-phase output, and a controller coupled to the boost converter and the 3-phase inverter. The controller can be configured to receive a voltage level of a power supply and a voltage level of a 3-phase inverter; compare a power threshold to at least one of: the voltage level of the power supply and the voltage level of the 3-phase inverter; and control an operation of the boost converter circuit to operate in a boost mode or a rectification mode based at least in part on the comparison.
