Wien Bridge Oscillator using Op Amp: This is also RC oscillator which uses RC type of feedback network. The main difference between phase shift and Wien bridge oscillator is that…
Op Amp Integrator Circuit: In an Op Amp Integrator Circuit, the output voltage is the integration of the input voltage. The integrators circuit can be obtained without using active devices…
Single Phase Synchronous Generator: Certain applications, usually restricted to less than 10 kVA are better served by a Single Phase Synchronous Generator. Examples are emergency, domestic/office supply, portable power for…
Parallel Operation of Synchronous Generator: We already know that synchronous machine connected to infinite bus-bars. Parallel Operation of Synchronous Generator of two finite size will be considered, which is the…
What is Synchronous Motor | Construction | Advantages: A synchronous Motor is one of the important types of electric machines; in fact all generating machines at power stations are of…
Self Excited DC Generator: Rather than arranging a separate dc source for excitation purposes, practical generators are always excited from their own armature terminals, this method of excitation being known…
Methods of Excitation of DC Generator: The performance characteristics of a dc machine are greatly influenced by the way in which the field winding is excited with direct current. There…
Introduction of DC Motor: Introduction of DC Motor is constructed in many forms and for a variety of purposes, from the 3-mm stepper drawing a few μA at 1.5 V…
