Load Commutated Chopper Circuit: In this method of Load Commutated Chopper Circuit, the load current flowing through the thyristor is made to become zero while the motor current is conducted by the free-wheeling diode. Figure…
Difference between Isolator and Circuit Breaker: The difference between Isolator and Circuit Breaker is given below Isolator: It is a manual operated device which is able to open or close a circuit during no load…
What is Voltage and Current? There are two quantities that we like to keep track of in electronic circuits : voltage and current. These are usually changing with time; otherwise nothing interesting in happening. Voltage…
Foldback Current Limiting Circuit: The disadvantage of constant current limit is relatively large power dissipation in the series pass transistor when the load terminals are shorted. Thus a large power rating transistor is required. The…
Battery Powered Vehicles: Battery Powered Vehicles - These are popularly known as electric vehicles. Although several batteries and fuel cells have been developed, only available at affordable price is the lead acid battery. Therefore, electric…
Symmetrical Optimum: Symmetrical Optimum - Sometimes automatic control systems contain integrating also besides first order delay elements, proportional elements and deadzones. Such a system when compensated on the basis of magnitude optimum discussed in the previous…
Sources of Fault Power: The sources of fault power originate in all the generating and other connected plants which under normal operating conditions draw power from the system. Mainly there are three sources which can…
Liquid Metal Cooled Reactor (LMCR) - Working, Advantages & Disadvantages: A liquid metal cooled reactor (LMCR) is an advanced type of nuclear reactor that uses a liquid metal as the primary coolant. The use of…
Static Scherbius Drive: The main limitation of the Kraemer drive discussed is the operation at sub-synchronous range due to diode rectifier. Super synchronous speeds can be achieved if the power is fed to the rotor…
Difference Between Frequency Modulation and Phase Modulation: The Difference Between Frequency Modulation and Phase Modulation are discussed below FM and PM are quite similar except by the manner in which the modulation index is defined.…
