摘要： The invention concerns a power back comprising a connection to a power supply network conveying alternating voltage with at least one transformer, a downstream rectifier circuit to which a consumer can be connected, and with an electronic switch in the transformer primary winding power-feed line. The power pack further comprises an auxiliary power pack which is capacitively connected to the power pack power-feed line and at whose output a control voltage can be tapped for the electronic switch, said control voltage being greater than the voltage at the power pack output, the auxiliary power pack output lead being connected to the potential-conveying lead on the secondary side of the power pack transformer. When a consumer is connected, current is taken from the auxiliary power pack, such that a control element operating as a function of the current and/or voltage generates in the power pack a control signal for the electronic switch in the power feed line of the transformer primary winding.

摘要： The invention relates to a method for signal processing an amplitude-modulated and/or phase-modulated high-frequency signal (RF signal), according to which the RF signal is divided into two signals (FM1 and FM2) by a relative phase shift by an angle of + beta and - beta , and the signals are amplified before they are added to form a transmit signal. The invention also relates to a circuit arrangement, in which the purely phase-modulated RF signal is multiplied in a first branch with cos beta and in a second branch with sin beta , and both signals (FM1, FM2) are obtained by respectively adding and subtracting the multiplied signals.
