摘要: In order to monitor the conduction cutoff phase angles of a plurality of controllable rectifiers arranged in two groups in a rectifier bridge, a signal proportional to the angle for each rectifier is stored in a respective sample and hold member after each occurrence of a positive blocking voltage at that rectifier, and the minimum of the currently stored signals is observed.

摘要: A modulation amplifier having an output amplifier element which contains an accumulation choke, a switching tube and a low-pass filter connected in series, with a commutation diode connected to the switching tube is disclosed. The switching tube is controlled by pulse duration-modulated pulses and a semiconductor switch is connected between the switching tube and the pulse duration-modulated pulses. The semiconductor switch comprises two branches, each of which are connected to a different electric potential and each including a controlled semiconductor which acts as a switch, one of the branches being controlled into a conducting state and the other of the branches being controlled into a non-conducting state upon a potential jump in the pulse time-modulated pulses in either the increasing or decreasing directions. The modulation amplifier may further include a control circuit for stabilizing at least one of the potentials, which comprises a switch element as a primary control element which is controlled by an auxiliary pulse duration-modulated signal. A chopper is provided with following filter means for providing an actual value to be fed to the control circuit, which is derived from the output voltage of the filter means.

摘要: The outer envelope of a capacitor body is provided with an insulation layer and at least the sides are surrounded in consecutive order by a first metal actuation layer, an insulation layer which is deformable or defusable under excess temperature, and a second metal actuation layer with the first metal actuation layer being connected to the first metal conductive layer and the second metal actuation layer being connected to the other metal conductive layer. The construction is such that if there is an increase in temperature in the capacitor body which, for example, may be caused by an overload or a defect, the insulation between the actuation layers will defuse or deform to the extent that the metal layers come in contact and produce a short-circuit which will be effective to throw the capacitor out of the line, such as, by a fusing action.
