    摘要： Power supply apparatus with overload protection comprising a switch responsive to an input signal for switching between an ON-state for supplying current from a source of power to a load and an OFF-state for interrupting the supply of current to the load, and protection means responsive to an overload condition to switch the switch to the OFF-state. The protection means is responsive to a first overload condition during an initial phase after the switch switches to the ON-state so as to switch the switch back to the OFF-state and maintain the switch in the OFF-state. The protection means is subsequently responsive to a second overload condition if the first overload condition is not detected during the initial phase so as to switch the switch to the OFF-state and subsequently switch the switch back to the ON-state after an interval of time.The protection means is responsive to the current exceeding a first threshold value in detecting the first overload condition, and is responsive to the current exceeding a second threshold value in detecting the second overload condition, the second threshold value being lower than the first threshold value. The protection means is responsive to a temperature of the switch means exceeding a temperature threshold value in detecting at least the first overload condition.

    摘要： Power switching apparatus comprising switch means having a control terminal and output terminals for connection in series between a power supply and a load. The switch means is responsive to a control signal applied to the control terminal to switch between an ON-state in which it supplies power supply current from the power supply through the output terminals to the load and an OFF-state in which it interrupts the supply of power through the output terminals to the load. The apparatus includes detection means for detecting an open-load condition of the load at least during the ON-state of the switch means, comprising detection control means operable in the ON-state of the switch means for modifying the control signal so as to start switching the switch means to the OFF-state during a lapse of time substantially less than the time required for the switch means to reach the OFF-state and for restoring the control signal to a value corresponding to the ON-state at or before the end of the lapse of time, and comparator means responsive to variation of voltage at the output terminals during the lapse of time. The duration of the variation of voltage during the open-load detection is too short and its magnitude too small for the variation of load current to be perceptible, notably in the case where the load is a lamp.

    摘要： 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.

    摘要： Disclosed is a method for pulse width modulated control of a plurality of load elements, particularly during supply of the load elements from a common supply system in motor vehicles. The load elements are controlled in a time staggered manner with respect to one another, more particularly in a phase staggered manner within a common pulse width. Switch loads and high frequency interferences in the supply lines and the corresponding emissions can thus be reduced. The invention also discloses a circuit arrangement in which a corresponding phase staggered control is achieved with only one counter.

    摘要： 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.
