Characteristics of separately excited DC Generator
The performance of a separately excited DC generator is analyzed with the help of three different characteristics: Magnetic or no-load or open circuit characteristics, internal or total characteristics and external…
Types of DC Generator and its equation
DC generators convert mechanical energy into electrical energy. For this conversion to take place, dc generators require a magnetic field. The magnetic field is produced by the field coil or…
EMF equation of a DC Generator
An emf is induced in a DC generator, when a conductor is rotated in a magnetic field. The emf induced in a conductor depends on the speed of rotation of…
Working Principle of DC Generator
A DC generator converts the mechanical input into an electrical output. The mechanical energy input is given to the dc generator by means of a prime mover. The prime mover…
Alternator on load
Whenever the load on the alternator is varied, the terminal voltage will also vary. This variation in terminal voltage is mainly due to three reasons: Voltage drop due to armature…
Armature reaction in Alternator or Synchronous Generator
Armature reaction is an important aspect in DC generator and AC synchronous Generator or Alternator. Armature reaction in alternator is defined as the effect of armature flux on the main…
EMF equation of alternator
The emf induced by the alternator or synchronous generator is three-phase alternating in nature. Let us derive the mathematical equation of emf induced in the alternator. Let, Z = number…
Design of parallel subtractor
The parallel subtractor is similar to the design of a parallel adder, both in its structure and operation. It is a combinational circuit, used to perform subtraction of multi-bit binary…
Design of Parallel Adder
Parallel adder is a combinational circuit, used to add multi-bit binary numbers. With half adder and full adder in use, What is the need for going to parallel adder? What…
