DC chopper
This is one stage conversion device which is used for direct conversion of fixed de voltage at a level to an adjustable dc voltage at another level.
Figure DC Chopper
Chopper is high speed on/ off semiconductor switch is represented by a switch SW with an arrow as shown no current will flow if the switch is off and when it is on current will flow in the direction of arrow only.
Buck Boost Converter The output of buck boost regulator may be less than or greater than the input voltage. Since the polarity of output voltage is opposite to that
Explain ferrites and its uses in high frequency devices. A group of magnetic alloys show the property of magnetisation that change, with percentage of various constituent atoms
General Purpose Registers Registers B, C ,D, E H , and L are 8 bit general purpose registers. These registers store 8 bit data temporarily for processing. Some
Types of Field-Effect Transistors The channel of a FET (field-effect transistor) is doped to produce either an N-type semiconductor or a P-type semiconductor. The drain and so
components and uses.
Registers A resister is a group of flip flops or binary cells which holds the binary information. Since a binary cell stores one bit of information an n bit regis
Q. Addition and integration can be combined by the summing integrator circuit shown in Figure. With the given component values and input waveforms, sketch v o when S is opened at
A circuit realization of a NAND gate will now be developed. By connecting NAND gates together in various ways, one can synthesize other gates and flip-flops. Thus in principle, a s
