Shaded pole induction motor is more or less similar to single-phase induction motor. The stator poles of this motor are wound only with main winding, so as to make them electromagnets. The pole has a slot cut at one third for one end for housing high reactance but low resistance copper bars enclosing a part

Figure 1. For pure metals, the resistance increases linearly with increase in temperature as shown in Fig. 1.8.2, and for a certain range of temperature (typically 0 to 100ºC) the rate of increase of resistance (slope of the line) remains constant. The resistance of metals reduces with reduction in temperature and it reduces to 0

The batteries are available with some specific terminal voltages. e.g. 1.5V, 6 V, 12 V, 24 V, 48 V etc. If we want to have some terminal voltage other than these standard ones, then series or parallel combination of the batteries should be done. One more reason for connecting the batteries in series or parallel

The cuk converter is dc to dc converter gives an output voltage which is less than or greater than the input voltage with a polarity reversal. That means, the polarity of output voltage is opposite to that of the input voltage. Figure 1 shows the cuk converter using BJT.
A TCR is a thyristor controlled inductor, connected in shunt with the line, in which the thyristor valve is controlled by partial conduction, in order to continuously vary the effective reactance of the line. TCR is a Variable impedance type static VAR generator, in which the reactor current can be varied by applying the firing
