    • An AC-DC voltage converter includes input terminals with a series circuit connected between the input terminals. The series circuit includes a switching element and a capacitor. The discharge of the capacitor supplies the output voltage of the converter. A control circuit controls the operation of the switching element so that the conducting state of the switching element is controlled exclusively as a function of the input voltage, while the nonconducting state of the switching element is controlled exclusively as a function of the output voltage. The converter has a good dynamic range and allows accurate measurement of current consumption at the output.
    • AC-DC电压转换器包括连接在输入端子之间的串联电路的输入端子。 串联电路包括开关元件和电容器。 电容器的放电提供转换器的输出电压。 控制电路控制开关元件的操作,使得开关元件的导通状态被专门地作为输入电压的函数来控制,而开关元件的非导通状态仅作为输出电压的函数被控制。 该转换器具有良好的动态范围,可以精确测量输出端的电流消耗。

    • A motor whose stator is equipped with a main winding (DP) and with an auxiliary winding which consists of two half-windings (B1, B2) that are wound in opposite directions and is supplied through a full-wave rectifier (GR) and by means of two commutating switches (T1, T2) controlled by a control circuit (COM) which alternately closes the switches at a frequency equal to the frequency of the supply voltage. The motor comprises, in parallel with the half-windings, at least one device (DAP) which limits the voltage across the terminals of the switches when they are opened, to a value higher than the supply voltage.
    • 一种电动机,其定子配备有主绕组(DP)和辅助绕组,该辅助绕组由两个绕相反方向缠绕并通过全波整流器(GR)供电的两个半绕组(B1,B2)组成,并由 由控制电路(COM)控制的两个换向开关(T1,T2)的装置,其以等于电源电压频率的频率交替闭合开关。 电动机与半绕组并联地包括至少一个装置(DAP),其将开关的端子两端的电压打开时限制到高于电源电压的值。
