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.
The single-phase, 50-kVA, 2400:240-V, 60-Hz, two-winding distribution transformer is connected as a step-up autotransformer, as shown in Figure. Assume that the 240-V winding is pr
Explain the different types of polarizations. Polarizations are of three types. i. Electric polarization ii. Ionic polarization. iii. Dipolar polarization.
Explain Contact resistance. Contact resistance: It is measured as the voltage drop from tail to tail of the mated contacts along with specified current flowing through the cont
