Application: Apparatus and/or system for providing pulsating buffer converter with a boost circuit (Patent ID: US20240006908A1)
The patent filed by Lear Corp describes a battery charger system that includes a transformer, two active bridges, and a pulsating buffer (PB) converter. The first active bridge generates a voltage signal from the mains supply, while the second active bridge stores this voltage on batteries. The PB converter, with multiple switching devices, modifies the voltage signal stored on the batteries by providing a voltage for storage on capacitors. The system aims to reduce current ripple and efficiently manage energy flow between the batteries and the electrical grid.
The claims of the patent detail the specific components and functions of the battery charger system, including controllers for switching devices, current ripple reduction, generation of alternating current inputs, and energy flow control. The system is designed to optimize the charging process by managing voltage signals, reducing ripple, and ensuring efficient energy transfer between batteries and the grid. Additionally, the patent covers variations of the system, such as different configurations of switching devices and transformers, to adapt the technology for various applications, including vehicle battery chargers.
