Abstract: Since parallel MOSFETs are usually driven with one gate signal in power applications, the current sharing between the MOSFETs is automatically established with regard to the characteristics of the individual MOSFETs. This may lead to a large non-uniformity of the current distribution between the MOSFETs. According to the present invention, an individual control of the on-resistances of the MOSFETs is provided, which allows for an improved current sharing between paralleled MOSFETs.

Abstract: The invention relates to a DC/DC down converter which includes a synchronous rectifier (S), a switching element (C)at its input side and an inductance (L) at its output side. In order to permit fast load fluctuations as well as to reduce costs and operating losses, it is proposed to provide an auxiliary circuit which comprises an auxiliary switching element (A), an auxiliary rectifier (Daux) and an auxiliary inductance (Laux), the auxiliary circuit being coupled to the connection between the synchronous rectifier, the switching element at the input side and the inductance at the output side.

Abstract: 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.

Abstract translation: 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。

Abstract: In known converter circuits switching losses occur, which are caused by reverse-recovery currents of a freewheeling diode. To reduce said switching losses it is proposed by the invention to drive the switching elements such that, upon switching from the second to the first switching element, the timing is controlled in such a manner that the shoot through currents and the conduction of the freewheeling diode are kept at a low value or, better still, are precluded. As regards the control mechanism, it is proposed to turn on the first switching element later if shoot through currents occur, and to turn on the first switching element sooner if conduction of the freewheeling diode occurs. Here, a time of overlap may be provided during which both switching elements are simultaneously conducting. For the control mechanism, the voltage across a switching element can be used as a measured input value.
