ydeepak297@gmail.com Primary of Transformer is connected to D.C. supply Q. What will happen if the Primary of the Transformer is connected to D.C. of the same Magnitude? A d.c. current will not produce the alternating flux and hence there will not be any self induced E.M.F. to oppose the supply voltage. Moreover the winding resistance is … Read more
UPS full form :- Uninterruptible Power Supply UPS PARTS NAME AND FUNCTION. Rectifier The rectifier carries out several key functions. The first is to convert the input power from AC (Alternating Current) to DC (Direct Current). Its second main role is to recharge the batteries, while the DC power routes to the inverter too. Depending … Read more
Pulse Transformer For coupling square wave or a pulse from primary to secondary the conventional transformer need change of shape of signal. Pulse transformer is a transformer which is designed to couple pulses from primary to the load connected to secondary without changing the shape of the pulse. Pulse transformers are used for coupling pulses … Read more

High Frequency Transformers In this category we study (1) Audio frequency (AF) transformer (2) Intermediate frequency (IF) transformer. (1) Audio Frequency (AF) Transformer Audio frequency range is 20 Hz to 20 kHz These transformers are especially designed for connecting different telephone systems to each other keeping their respective power supplies ‘isolated’. Following are the functions … Read more

Core Cross Section For small core type transformers simple rectangular section limbs with rectangular coils are used. However for large capacity transformers circular coils are used instead of rectangular coils, as a circle gives reduced length of mean turn (due to minimum perimeter for a particular area) which reduces requirement of conductor material, which in … Read more
A starter will contain protective devices for the motor. At a minimum this would include a thermal overload relay. The thermal overload is designed to open the starting circuit and thus cut the power to the motor in the event of the motor drawing too much current from the supply for an extended time. The … Read more
