Abstract: Power control systems are provided including a digital controller configured to control gating mechanism for power switches responsive to an input from a power conversion circuit. The digital controller includes a conversion circuit, a modulation circuit and a gating control circuit. The system further includes an analog circuit comprising a filter, a current limiter and a compare circuit. The current limiter is configured to control a magnitude of a current pulled through a power convertor during a device switching operation.

Abstract: Disclosed is a power inductor. The inductor comprises a magnetic core and multiple lines. The multiple lines have a first terminal and a second terminal, are parallel with each other, and wind the magnetic core to form a winding. The lines at the first terminal depart from the magnetic core at the same position, and the lines at the second terminal depart from the magnetic core at the same position. At least one line at the first terminal forms a first interface end, the other lines at the first terminal, which are not utilized to form the first interface end, form a second interface end, and the lines at the second terminal together form a third interface end. By measuring the current flowing through the first interface end using a current sensor with a small measuring range, the current flowing through the power inductor can be estimated based on ratio.

Abstract translation: 公开了一种功率电感器。 电感器包括磁芯和多条线。 多条线具有第一端子和第二端子，彼此平行，并且缠绕磁芯以形成绕组。 第一端子处的线在相同位置处离开磁芯，并且第二端子处的线在相同位置处离开磁芯。 在第一端子处的至少一条线形成第一接口端，不用于形成第一接口端的第一端子处的其它线路形成第二接口端，并且第二端子处的线路一起形成第三端口 接口端 通过使用具有小测量范围的电流传感器测量流过第一接口端的电流，可以基于比率来估计流过功率电感器的电流。
