Power supply system for aircraft with variable voltage conversion
The patent US12046896B2 describes a sophisticated power supply system designed for aircraft applications. The system includes a DC power source that provides variable bulk voltage, which is then processed by two DC/DC converters. The first converter elevates the DC power to a high voltage suitable for high-voltage loads, while the second converter reduces this power to a low voltage for low-voltage loads. A protection circuit is integrated to selectively manage the transfer of power to the high-voltage load, ensuring that the first converter operates effectively when the variable bulk voltage meets or exceeds the high voltage requirements. The system is equipped to handle various error conditions, such as undervoltage, overvoltage, overcurrent, and high temperature, through a series of sensors and a monitoring circuit that can indicate power availability.
Additionally, the power supply features a start and backup input circuit that can receive power from a backup source, with safeguards to prevent backflow of power. The second DC/DC converter is designed with galvanic isolation and includes internal components for converting and transferring power efficiently. The main AC/DC converter, which is integral to the system, can receive AC power from an external source, such as a generator driven by an aircraft engine, and is capable of delivering the necessary DC power to the converters. This innovative design aims to enhance the reliability and safety of power distribution in aircraft, catering to both high-voltage and low-voltage electrical systems.
