Mode 1 ( 0
By applying a positive output pulse of the pulse width modulator to the transistor Q1 it gets turned on. An input current in flows through Vin Q1 inductor L and then divides into two parts one flows through capacitor C and other through load.
In this mode inductance stores the energy and induced voltage in inductor bunks the input voltage.
Many circuits, particularly amplifiers, use negative feedback (nfb) in order to function reliably. The nfb changes the performance of the circuit to which it is applied, in most ca
Variable Frequency Systems In this systems the chopping period T will varying but either Ton is kept constant or T off kept constant. In any case the off time T off w
Low-pass electronic filter: The capacitors and inductors are the reactive elements of the filter. The number of elements ascertains the order of the filter. In this situation,
Q. What do you mean by Retention of Risk? Retention of Risk: In case of this method, the organization voluntarily accepts the risk since either the risk is insignificant or its
Systems such as those encountered in mechanics, thermodynamics, and hydraulics can be represented by analogous electric networks, from the response of which the system characterist
Q. What is the difference between field effect transistor and the bipolar junction transistor? The important points of the comparison between the field effect transistor ands t
In terms of negative feedback, there exists an analogy between the operational amplifier and the power-steering mechanism of an automobile. The hydraulic pump is analogous to the p
Aloudspeaker is a common electrochemical transducer in which vibration is caused by changes in the input current to a coil which, in turn, is coupled to a magnetic structure that c
(a) contains a freewheeling diode Dm, commonly connected across an inductive load to provide a path for the current in the inductive load when the switch S is opened after time t (
Explain the term simplex transmission. Data in a simplex channel is always one method. Simplex channels are not frequently used because this is not possible to send back error
