SIMPLIFIED MAGNETIC AMPLIFIER CIRCUITRY If the saturable-core reactor works, why do we need to add a rectifier to produce a magnetic amplifier? To answer this question, recall that in NEETS, module 2 – Introduction to Alternating Current and Transformers, you were told about hysteresis loss. Hysteresis loss occurs because the a.c. applied to a coil […]

Scaling amplifier , difference amplifier , circuit for q31 through q33 , circuit for q36 through q38 , magnetic amplifiers , methods of changing inductance , flux paths in a saturable-core reactor and flux aiding
Scaling amplifier One final type of summing amplifier is the SCALING AMPLIFIER. This circuit multiplies each input by a factor (the factor is determined by circuit design) and then adds these values together. The factor that is used to multiply each input is determined by the ratio of the feedback resistor to the input resistor. […]

Current flow in the operational circuit , bandwidth limitations and applications of operational amplifiers
Current flow in the operational circuit You can compute the values for view (C) and prove that point A in that circuit is also at virtual ground. The whole point is that the inverting input to the operational amplifier shown in figure 3-13 is at virtual ground since it is at 0 volts (for all […]
