Publication number: 20250211220Abstract: A power converter having an integrated input bias self-supply function has an input switch, a controller, an output switch, and an output filter having an inductor. The controller includes control circuitry, a bias drive circuit, and a bias supply circuit. The bias supply circuit includes a bias transistor and a bias diode. The control circuitry and the bias drive circuit produce a bias drive signal indicative of the conductive states of the input and output switches. When the bias drive signal is asserted, the bias transistor is configured to be on and the bias diode is configured to be reverse biased and not conduct any forward current. When the bias drive signal is deasserted, the bias transistor is configured to be off.Type: ApplicationFiled: December 21, 2023Publication date: June 26, 2025Applicant: POWER INTEGRATIONS, INC.Inventor: DAVID MICHAEL HUGH MATTHEWS

Publication number: 20250198113Abstract: A coupler for securing an attachment to an earth working machine. The coupler comprises a coupler body that presents a receptacle having a capture region. A pin of an attachment can move into and out of the capture region. A retainer can capture the pin in the capture region but the retainer can be moved by a hydraulically driven driver to a position to allow release the pin from the capture region. A trigger that the pin will strike when the pin moves into or out of the capture region, decouples the driver from the retainer and the retainer is then allowed to be biased back to its retaining position by a spring.Type: ApplicationFiled: March 2, 2025Publication date: June 19, 2025Applicant: WEDGELOCK EQUIPMENT LIMITEDInventors: Andre Richard ANDERSON, Garth Colin KEIGHLEY, Andrew James Phillip RIDER, Michael Hugh James RIDER
