    • A controller is described, which is particularly suited for a power supply with switching elements (S1, S2), such as a switching mode power supply. The controller comprises a logical unit (18) which calculates a binary state value Z k by a first logical operation from a binary input value I and a prior binary state value Z k- 1 . The logical unit further calculates a binary output value Y by a second logical operation from the binary input value I and the binary state value Z k . In this way, fast and efficient fully digital control may be realized especially for a switching mode power supply, where the binary input value I is a comparator value and the binary output value Y is used to drive the switch elements (S1, S2). An adaptation unit (20), which may be a signal processor, determines the logical operations and delivers them to the logical unit (18) during operation of the controller unit (16).
    • 描述了一种控制器,其特别适用于具有开关元件(S1,S2)的电源,例如开关模式电源。 该控制器包括一个逻辑单元(18),该逻辑单元(18)通过来自二进制输入值I和现有二进制状态值Z k-1的第一逻辑运算来计算二进制状态值Z < SUB>。 逻辑单元还通过来自二进制输入值I和二进制状态值Z 的第二逻辑运算来计算二进制输出值Y. 以这种方式,可以实现快速高效的全数字控制,特别是对于二进制输入值I是比较器值并且二进制输出值Y用于驱动开关元件(S1,S2)的开关模式电源。 可以是信号处理器的适配单元(20)在控制器单元(16)的操作期间确定逻辑操作并将其传送到逻辑单元(18)。

    • The invention relates to an electronic circuit and to a method of supplying a high-pressure discharge arc lamp (12). The circuit comprises a DC-AC converter, for which purpose two controllable switching elements T1, T2 are connected in the form of a half bridge to an operating potential U+ and a reference potential (10). The circuit further comprises a two-stage filter arrangement. The lamp is connected to a coil Lign of the second filter stage, and the same connection terminal of this coil L ign is connected to the reference potential (10) via a capacitor C ign . To make the circuit as small and as economical as possible, while high high-frequency interference peaks and strong currents in the circuit are avoided, it is proposed that a coil Tr filt of the first filter stage has at least three taps. The first, outer tap is connected to the output of the half bridge, the second, central tap to the second connection terminal of the coil L ign , and the third, outer tap to the reference potential (10) via a capacitor C filt .

    • The invention relates to an electronic circuit for igniting a high-pressure lamp. A resonant circuit 13 of the circuit is used to supply the ignition voltage for the high-pressure lamp. To enable an exact adjustment of the resonance frequency in the resonant circuit, it is proposed that the circuit also comprises converter 12 for generating an alternating voltage with which the resonant circuit 13 is excited and an oscillator 14, 16, 17 for driving the converter 12, the fundamental frequency of the output voltage of the oscillator being at least in proximity to an integral fraction of the resonance frequency of the resonant circuit 13. Finally, it is proposed that the circuit includes a feedback 17 from the resonant circuit 13 to the oscillator 14, 16, 17, whereby the fundamental frequency of the output voltage of the oscillator is so tuned that the resulting frequency of the output voltage of the oscillator corresponds substantially exactly to the integral fraction of the resonance frequency.

    • The invention relates to an electronic circuit and a method of supplying energy to a high-pressure gas-discharge lamp H, 65, 75. The electronic circuit comprises a line-supply input section 62, 72 to receive and convert an a.c. voltage from an a.c. line-supply system 61, 71, an energy storage means 63, 73 to store the energy put out by the line-supply input section 62, 72 and a lamp-current regulating unit 64, 74 that is supplied with an input voltage U1 by the line-supply input section 62, 72 via the energy storage means 63, 73 and that makes available a lamp current I2 for a high-pressure gas-discharge lamp H, 65, 75. To make it possible for the energy storage means 63, 73 to be particularly small, it is proposed that the lamp-current regulating unit 64, 74 have a power section L, D, C, S, A1, A2, K having a transconductive property. If there is a drop in the input voltage U1, this property then automatically produces a reduction in the lamp current I2 made available to a high-pressure gas-discharge lamp 65, 75, H. This ensures a particularly fast adjustment to voltage fluctuations. The invention also relates to a corresponding method.
