4-57. A simplified block diagram of the regulated output). A sensor or differential amplifier senses
power supplies is shown in figure 4-9. Each series any change in the output voltage by comparing the
regulator acts as a variable resistance in series with output against a reference voltage. The amplifier
each supply output (even if the series regulator is in then changes the effective resistance of the series
the return leg of the supply, as in the +110 volt and regulator, and thereby the voltage drop across it, to
+370 volt returns, the regulator is in series with the oppose the change in output voltage.
