摘要： Resonant gate driver circuits provide for efficient switching of, for example, a MOSFET. However, often an operation of the resonant gate driver circuit does not allow for an application where high switching frequencies are required. According to the present invention, a pre-charging of the inductor of the resonant gate driver circuit is performed. This allows for a highly efficient and fast operation of the MOSFETs.

摘要： Usually, power supplies are not capable of switching off part of the outputs of a main power supply during stand-by. Due to this, stand-by power supplies are used in addition to operation power supplies. Consistent with an example embodiment, a forward converter is provided, including switches in the rectifier circuit thereof. Due to this, the rectifier circuits may be selectively switched on and off. Advantageously, this may allow that the main outputs of such a forward converter are switched off while on stand-by.

摘要： 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 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.
摘要翻译：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。许多相同的光电二极管DA 1 DAn在正向模式下的串联电路（A）允许实现具有晶体管（T）的受控电流源（6），因为整体布置的容许二极管电压（Ud）可以具有 n倍于单个光电二极管的工作电压值。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。

摘要： In a switching DC converter with a resonant circuit output stage, the energy remaining in the resonant circuit for switching the switches of the converter in an inductive mode of operation is used to control the phase of switching. The turn-on phase of each switch is controlled to assure zero voltage switching, and the turn-off phase of each switch is controlled to assure that the resonant circuit has sufficient energy to provide this zero voltage switching.
