    • The system, which provides a control signal, includes an over-current control unit, a time clock that provides a periodic time signal, and a clock generator unit that includes a first input terminal, a second input terminal, and an output terminal. The first input terminal is coupled to the time clock and the output terminal is coupled to the over-current control unit. The first input terminal of the clock generator unit receives the periodic time signal and the second input terminal of the clock generator unit receives a modification signal. The clock generator unit generates a clock signal based on the periodic time signal and the modification signal. The output terminal of the clock generator unit provides the clock signal to the over-current control unit, and the over-current control unit provides a control signal based on the clock signal.

    • The invention introduces a method for the production of an output signal having a predefined average size from a relatively larger input signal by pulse-width modulated connection of the input signal, wherein the pulse-width modulation has a predefined number of discrete, adjustable pulse widths within a pulse width and each pulse width corresponds to a specific average output-signal size. A super frame consisting of at least two successive pulses is chosen in order to produce an output signal which has an average size and which does not correspond to one of the discretely adjustable pulse widths. At least two pulses inside the super frame have a different pulse width such that the average output signal size corresponds to the predefined size. As a result, it is possible to produce intermediate average size values which can not be represented by a pulse width, in addition to such average size values which can not be produced as a result of the switching delay of the pulse-width modulation controlled switching means in a pulse width.
    • 本发明引入了一种用于通过输入信号的脉冲宽度调制连接从相对较大的输入信号产生具有预定平均尺寸的输出信号的方法,其中脉冲宽度调制具有预定数量的离散可调脉冲宽度 在脉冲宽度内,每个脉冲宽度对应于特定的平均输出信号尺寸。 选择由至少两个连续脉冲组成的超帧,以便产生具有平均尺寸并且不对应于离散可调脉冲宽度之一的输出信号。 超帧内的至少两个脉冲具有不同的脉冲宽度,使得平均输出信号大小对应于预定义的大小。 结果,除了由于脉冲宽度调制控制切换的切换延迟而不能产生的平均尺寸值之外,还可以产生不能由脉冲宽度表示的中间平均尺寸值 意味着脉冲宽度。
