    摘要: The invention relates to an electronic ballast comprising a step-up converter for operating a discharge lamp. The electronic ballast is embodied in such a way as to disconnect a switching element (T1) in the step-up converter when a maximum current value of the current flowing through the switching element is reached. The electronic ballast comprises a holding circuit (HS) which is provided with a time-function element (R27, C23) and is embodied in such a way that it sets the time-function element (R27, C23) when the switching element (TI) is disconnected and reconnects the switching element after a time interval defined by the time-function element (R27, C23).

    摘要: The invention relates to an electronic ballast comprising a converter which is used to operate a discharge lamp, for example, a low pressure discharge lamp, for selectively operating, in a direct manner, the supply network or a phase section dimmer. Jumps in the supply voltage are decoupled by a differential which is connected between at least one of the network lines and the reference potential of the ballast and transmitted to a control of the ballast, such that the control of the converter can distinguish between the operation on the phase section dimmer and on the network supply.

    摘要: A circuit including a voltage-controlled transistor to be switched. A first transistor is switched on, mediated by a control signal, and a first current flows through a series circuit and starts to subject a control input of the voltage-controlled transistor to charge reversal. The first current brings about a first potential shift at a connecting node. A second transistor is switched on by this first potential shift and a second current therefore flows through the switching path of the second transistor into the control input of the first transistor, which amplifies the first current. The increasing charge reversal of the control input of the voltage-controlled transistor brings about a second potential shift at the connecting node, the second transistor is switched off by this second potential shift, and the first transistor remains switched on, however, and holds the voltage-controlled transistor in its new switching state.

    摘要: A ballast having a dimming device for a low-pressure discharge lamp. For brightness control, the DC component of the periodically modulated envelope of the lamp current is varied. In this case, the current does not fall below predetermined minimum values for the lamp current. Phases with a high lamp current are characterized by a steep rising edge, compared with a flatter falling edge.
