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.
Q. Draw and explain an RC integrator .Derive the relation between input and output voltage. Solution: A circuit in which the output voltage is directly proportional to the
Currents induced in armature conductors of a d.c. generator are alternating. To make their flow unidirectional in the external circuit, we need a commutator. Moreover, these curren
Explain the construction of a MOSFET. Draw the symbols and diagrams of both P-channel and N-channel MOSFET. As JFET and MOSFET also have source, drain and gate. Its gate is ins

PUSH PSW Instruction It is similar to above push instruction but instead of normal register Paris it use PSW as its operand. Program status word comprises of the content
Three transformers are provided with the following rating values: 1) 2400/240 V, 55kVA, Req1 = (0.1 + 0.0Y) Ohm and Xeq1 = (0.15 + 0.XX) Ohm. 2) 240/120 V, 25kVA, Req1 = (0.1
advantages and disadvantages of inductive coupling
Q. Show DC Generator Characteristics? Figure shows schematic diagrams of field-circuit connections for dc machines without including commutating pole or compensating windings.
Assume that an abrupt Si p-n junction with area 10-4 cm2 has NA=10 17 /cm 3 and ND=10 17 /cm 3 is working at room temperature. It is given that μ n = 700 cm 2 /v-s, μ P =250 cm
