Abstract
Abstract The voltage control has the a.c. input received by a rectifier Ä3Ü with the output coupled to a regulating device Ä6Ü providing the dc voltage. The device has a control input Ä9Ü. The output Ä7Ü is fed back as an input to a differencing amplifier Ä10Ü that has a reference on the other input Ä11Ü and is connected Ä14Ü as an integrator. The output signal is multiplied Ä17Ü by the rectified signal and the result amplified to operate a drive stage Ä21Ü to control the regulating device Ä6Ü. When the reference voltage signal is exceeded a turn off signal is produced. <IMAGE>
