Application: Low voltage, low frequency, multi level power converter (Patent ID: US20230412091A1)

The patent filed by Jabil Inc. discloses a low voltage, low frequency multi-level power converter designed for power conversion. The converter includes phase-shifting inverters in series, each generating a square wave output from low voltage inputs, which is then smoothed to a semi-sine wave output by a voltage regulator. The converter is particularly suitable for photovoltaic applications, with each low voltage input associated with a photovoltaic cell, and can be integrated with various PV modules such as maximum power point tracking systems and arc fault protection circuits.

The power converter's design ensures a low level of total harmonic distortion, regardless of the load being driven. It also features integration circuitry for combining low voltage inputs with the inverters, as well as dedicated module-level controllers for enhanced functionality. The semi-sine wave output produced by the converter can be connected to a utility grid, making it a versatile and efficient solution for power conversion needs. Additionally, the inverters are switched at a low frequency, typically between 50 Hz to 60 Hz, and the voltage regulator may comprise a full bridge converter for optimal performance.
