Latest Patents

Bernard Keogh holds a patent for "Primary-side sensing arrangements for power converters." This invention involves a sensing arrangement and method where a sense winding is utilized to provide a voltage that represents the voltage across an in-circuit magnetic component. During the flyback phase, when the component supplies the output, the voltage reflects the output voltage, while in the supply phase, it represents the supply voltage. This arrangement effectively resolves the issue of disparity in the magnitude of sense winding output during these two phases. It incorporates a pull-up resistor that applies bias to the measured voltage, with different levels during the supply and flyback periods. This invention is particularly suitable for transformer-based flyback power converters, where the magnitude disparity problem can be exacerbated by the turns ratio.
