    Abstract: In a low voltage power supply, a plurality of different low voltage outputs are provided at different voltage magnitudes, the series choke of each of the output is wound on the same ferromagnetic structure (core), the number of turns in the choke of each output being different and related to the number of turns in the choke of the other outputs in the same ratio as the relationship of their voltage magnitudes, thereby to provide the same volts per turn on each of the choke windings on the common core. In a second embodiment, only some of the output chokes are driven by rectifiers fed by the transformer secondary, the remaining supplies being driven by means of transformer action through the filter chokes themselves.

    Abstract translation: 在低压电源中,以不同的电压幅度提供多个不同的低电压输出,每个输出的串联扼流圈缠绕在相同的铁磁结构(磁芯)上,每个输出的扼流圈的匝数 与其他输出的扼流圈的匝数与其电压幅度的关系相同,从而在公共芯上的每个扼流绕组上提供相同的每匝电压。 在第二实施例中,只有一些输出扼流器由变压器次级馈电的整流器驱动,剩余的电源通过变压器作用通过过滤器扼流圈自身驱动。
