    • A method and device for charging and/or discharging a capacitive element. A controllable switch is driven to interrupt the charging current when the charging current exceeds a predetermined charging-current threshold. The charging-current threshold is altered while the capacitive element is being charged to the predefined charging voltage. The controllable switch is driven again for coupling the charging current into the capacitive element if a predefined period of time after a previous activation of the controllable switch has elapsed, and/or in case the charging current drops below the predetermined charging-current threshold. A discharging process is carried out correspondingly.
    • 一种用于对电容元件充电和/或放电的方法和装置。 当充电电流超过预定的充电电流阈值时,驱动可控开关来中断充电电流。 当电容元件被充电到预定充电电压时,充电电流阈值被改变。 如果经过可控开关的先前激活之后的预定时间段和/或在充电电流下降到低于预定充电电流阈值的情况下,则再次驱动可控开关以将充电电流耦合到电容元件。 相应地进行放电处理。

    • An infrared emitter element includes: at last one emitter tube made of silica glass, which has two ends; at least one electrical conductor arranged in the emitter tube as a radiation source; a cooling tube made of silica glass, which surrounds the at least one emitter tube spaced therefrom and which is connected to the at least one emitter tube directly at its ends, such that in the region of the electrical conductor at least one flow-supporting channel is formed between the at least one emitter tube and the cooling tube; and a metallic reflector. The cooling tube is completely covered with the reflector on its side facing away from the emitter tube. The infrared emitter element may be used as a flow-through heater, such as a heat exchanger, especially for high-purity fluids.
