Description
образом, на выходе усилител 2 развиваетс переменное напр жение, равное напр жению на контролируемом объекте 3, Выравнивание потенциалов на входе и выходе усилител 2 за счет положительной обратной св зи ведет к возрастанию эффективного значени сопротивлени ,удл переменного тока.Thus, at the output of the amplifier 2, an alternating voltage equal to the voltage at the controlled object 3 develops. Equalizing the potentials at the input and output of the amplifier 2 due to positive feedback leads to an increase in the effective value of the resistance, alternating current.
Выравнивание потенциалов и увеличение выходного сопротивлени усилител 2 переменного тока приводит к устранению шунтировани переменного напр жени через внутреннее сопротиление источника 4 поп ризутащего напр жени и выходное сопротивление усилител 2.Equalizing the potentials and increasing the output impedance of the AC amplifier 2 leads to the elimination of the shunting of the alternating voltage through the internal resistance of the source 4 of the impeding voltage and the output impedance of the amplifier 2.
Таким образом, включение источника пол ризующего напр жени между входом и выходом усилител переменного тока с коэффициентом усилени , равным 1, обеспечивает хорошую разв зку цепей пол ризации и переменного тока без использовани дополнительных сопротивлений Z. и Z в цепи источника пол ризуюц его напр жени , что позвол ет /упростить схему усилител переменного . тока и всего устройства и значительно уменьшить потери мощности в цеп х разв зки, обеспечива , тем самым, возможность работы с пол ризующими токами больших значений, т.е. с реальными гальваническими ваннами.Thus, turning on the source of a polarizing voltage between the input and output of an AC amplifier with a gain of 1 ensures good isolation of the polarization and AC circuits without using additional resistance Z. and Z in the circuit of the source polarizing its voltage, which allows / simplifies the variable amplifier circuit. current and the entire device and significantly reduce power losses in the isolation circuits, thus providing the ability to work with polarizing currents of high values, i.e. with real electroplating baths.
