    • A control unit (2) of a remote control receiver sets the forward or reverse direction operating mode of the photodiode (1) as a function of the useful signal level of its output signal, and to be precise, during standby, the photovoltaic operating mode (forward mode), since in this mode no external bias current is required. If the useful signal level of the photodiode (1) exceeds a predefined threshold, the reverse mode is set, and this brings with it a higher sensitivity. A series circuit (A) of a number of identical photodiodes DA1... DAn in the forward mode allows the realization of a controlled current source (6) having a transistor (T), since the permissible diode voltage (Ud) of the overall arrangement may have n times the value of the operating voltage of an individual photodiode. Thus at the same time the voltage across the individual diodes can be set to a very low value and a favorable operating range for the current source can be set. The possible sensitivity of the receiver module having diodes in this operating mode can thereby be considerably increased.
    • 遥控接收器的控制单元(2)根据其输出信号的有用信号电平来设置光电二极管(1)的正向或反向操作模式,并且准确地说,在待机期间,光伏操作模式 (正向模式),因为在此模式下不需要外部偏置电流。 如果光电二极管(1)的有用信号电平超过预定义的阈值,则反向模式被设置,并带来更高的灵敏度。 正向模式中的多个相同光电二极管DA1 ... DAn的串联电路(A)允许实现具有晶体管(T)的受控电流源(6),因为总体上允许的二极管电压(Ud) 布置可以具有单个光电二极管的工作电压值的n倍。 因此,同时,可以将各个二极管两端的电压设置为非常低的值,并且可以设置用于电流源的有利的工作范围。 因此,可以显着增加在该操作模式中具有二极管的接收器模块的可能灵敏度。

    • The invention relates to a method of regulating the power supply for two or more power consumers, wherein at least two of the power consumers are connected to a direct-voltage source (1) via at least a respective voltage regulator (21a, 21b, 22, ... 2n) and wherein each voltage regulator (21a, 21b, 22, ...2n) is supplied with an input voltage (Uin,a, Uin,1b, Uin,2, ..., Uin,n) by the direct-voltage source (1) and supplies one of the power consumers with a steady voltage (Uout,1a, Uout,1b, Uout,2, ... Uout,n). In order to optimize the voltage supply and to avoid high power losses and heat losses, it is proposed that a) for each voltage regulator (21a, 21b, 22, ... 2n) a control signal is generated that is dependent at least on the applied input voltage (Uin,1a, Uin,1b, Uin,2, ... Uin,n) and on a specific reference value (Vref,1a, Vref,1b, Vref,2, ..., Vref,n) for the voltage regulator (21a, 21b, 22, ... 2n) and b) the input voltages (Uin,1a, Uin,1b, Uin,2, ... Uin,n) are regulated by the direct-voltage source (1) as a function of at least one of the generated control signals.

Uin,n)由直流电压 源(1)作为所生成的控制信号中的至少一个的函数。
