Patent number: 12348121Abstract: A transitional USB receptacle has one USB PD port and one USB-C port (non-PD). The receptacle includes flyback topology for AC/DC conversion, a bypass circuit, a buck converter, and a USB controller that determines the voltage demands of external devices connected to the USB-C and PD ports. The flyback topology uses a transformer with two sets of windings that produce different output voltages. The bypass switch is configured to ensure that only voltage signals under 10V are input to the buck converter, resulting in a different one of the transformer output voltages being input to the buck converter under different load demands. This enables the buck converter to more efficiently produce a 5V at the USB-C port when the USB PD port needs to simultaneously supply either 15V or 20V, and also enables the buck converter to more efficiently produce a 5V or 9V output at the USB PD port.Type: GrantFiled: September 8, 2023Date of Patent: July 1, 2025Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Nilesh Ankush Kadam, Stanislav Popelka

Patent number: 12334850Abstract: Inventive concepts herein relate to mitigating phase current oscillations and vibrations in a spinning, lightly loaded three-phase electric motor. A motor starter can transition between various acceleration profiles defined by unique firing angles and/or firing angle rates of change. These transitions adjust the firing angle of thyristors, which directly manage each phase of a three-phase power supply to the motor. The motor start can identify when a motor has residual motion from prior operation and can modulate the firing angle and/or firing angle rate of change accordingly to reduce a duration of time that issues such as phase current oscillations or vibrations might occur.Type: GrantFiled: September 5, 2023Date of Patent: June 17, 2025Assignee: Eaton Intelligent Power LimitedInventors: Stan Simms, Gabriel Teixeira Braga
