发明名称 DEVICE FOR THE PROTECTION OF AN AMPLIFIER AGAINST REACTIVE CURRENTS,HARMFUL DISTURBING CURRENTS OR THE LIKE AT THE OUTPUT OF THE AMPLIFIER
摘要 The intention of this invention is to make a device in which reactive currents or other disturbing currents appearing on the output of the amplifier with high efficiency will be drawn off and charge e.g. accumulators or capacitors. An amplifier (1), which is supposed to have the gain (1) and shall be protected for positive input voltages, is on the output connected to a chain of transistors (2, 6) with the emitters and collectors in series. Every collector is via diods (3, 7) connected to connections in a chain of accumulators (4, 8), which are connected in series. Every base is via bias voltages (5, 9) connected to the input of the amplifier. The bias voltages are so chosen that if the input voltage is positive and the output voltage is further positive, due to reactive effect, the output will be load by a current via emitter and collector in the transistor (2) and the diode (3) to the accumulator (4), if the output voltage is high enough. Should the output voltage be smaller, the current will go also through emitter and collector in the transistor (6) and then through the diode (7) to accumulator (8).
