摘要： A method for driving a non-linear load element. On account of the non-linear interrelationship between the voltage and the current at the load element and the related non-linear dependence of the power loss on the quantities “voltage” and “current”, an adjustment of the switching speed only on the basis of the power loss in the switching element cannot be carried out with non-linear load elements without being confronted with undesirable switching losses and related electromagnetic noise fields. Therefore, the load current currently flowing in the load element is picked up in addition to the currently determined power loss in the switching element, and the switching speed of the switching element is controlled in dependence on the determined power loss and on the current picked up. The switching speed can be optimally adjusted when driving the non-linear load elements by means of PWM.

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.
摘要翻译：具有过载保护的电源设备包括响应于输入信号的开关，用于在从电源提供电流到负载的电流的接通状态和用于中断向负载提供电流的断开状态之间切换;以及保护装置响应于过载条件将开关切换到OFF状态。保护装置在开关切换到接通状态之后的初始阶段期间响应于第一过载状况，以将开关切换回关断状态并将开关保持在关闭状态。如果在初始阶段期间没有检测到第一过载条件，则保护装置随后响应于第二过载状况，以便将开关切换到关闭状态，并且随后在一段时间之后将开关切换回接通状态。在检测到第一过载状态时，保护装置响应于超过第一阈值的电流，并且响应于在检测到第二过载状况时超过第二阈值的电流，第二阈值低于第一阈值。至少在检测到第一过载条件时，保护装置响应于开关装置的温度超过温度阈值。
