A dual converter is an electronic device that combines two bridges, where one bridge acts as a rectifier to convert AC to DC and the other acts as an inverter to convert DC back to AC. There are two main types - single phase and three phase dual converters. In operation, one converter acts as a rectifier while the other acts as an inverter to provide reversible DC power. Dual converters are commonly used for speed control of DC motors in industrial applications where reversible DC power is required.Unit 2 - DC-Motor-Drives-pptx.pptx

Inverters
A circuit that converts dc power into ac power at desired output voltage and frequency is called an inverter. Some industrial applications of inverters are for adjustable speed ac drives, induction heating, standby aircraft power supplies, UPS (Uninterruptable Power Supplies) for computers, HVDC Transmission lines etc. Phase controlled converters when operated in inverter mode are called line commutated inverters.
The dc power input to the inverter is obtained from an existing power supply network or from a rotating alternator through a rectifier or a battery, fuel cell, PV array, MHD (Magneto Hydrodynamic) generator. The configuration of ac to dc converter and dc to ac inverter is called a dc-link converter. Inverters can be broadly classified into two types:
Voltage Source Inverters (VSI)
Current Source Inverters (CSI)
Voltage Source Inverters (VSI) is one in which the dc source has small or negligible internal impedance. In other words, a dc voltage source has stiff dc voltage source at its input terminals.
Current Source Inverters (CSI) is fed with adjustable current from a dc source of high internal impedance i.e. from a stiff dc current source. It is fed with stiff current source, output current waves are not affected by the load.
From the viewpoint of connections of semiconductor devices, inverters are classified as under:
Bridge Inverters.
Series Inverters.
Parallel Inverters.
Single Phase Voltage Source Inverters
Single Phase Bridge Inverters: Single phase bridge inverters are of two types:
Single phase half Bridge Inverters.
Single Phase Full Bridge Inverters.
Single Phase Half Bridge Inverters: The voltage waveforms are drawn for the assumption that each thyristor conducts for the duration its gate pulse is present and is commutated as soon as this pulse is removed. It consists of two SCRs, two diodes and three-wire supply. For the cycle 0 <t <T/2, thyrsitors T conducts and the load is subjected to a voltage V/2 due to the upper voltage source V/2. At t = T/2, thyristor T is commutated and T is gated on. During the period T/2 < t < T, thyristor T conducts and the load is subjected to a voltage (-V/2) due to the lower voltage source V/2. from the waveforms it has been seen that load voltage is an alternating voltage waveform of amplitude V/2 and of frequency 1/T Hz. Frequency of the inverter output voltage can be change by controlling T. The main drawback of half-bridge inverter is that it requires 3-wire dc supply. This difficulty can, however be overcome by the use of a full-bridge inverter.

Cycloconverters are static frequency changers that can produce adjustable voltage and frequency AC power from a constant voltage AC source without an intermediate DC link. They use naturally commutated thyristors in configurations such as single phase to single phase, single phase to three phase, and three phase to three phase. Cycloconverters see applications in drives for machines like cement mills, ship propulsion, rolling mills, and ore grinding mills. They have advantages like not requiring an intermediate DC stage and suitability for large, low speed drives. However, they require a large number of thyristors and are limited to an output frequency of one-third the input frequency.Buck boost converter

Three-phase transformers are used for power generation and transmission because they are more efficient and cost-effective than single-phase transformers. They have three cores arranged 120 degrees apart that operate on the principle that the fluxes in each core sum to zero at any given time. Various winding configurations like star-star, delta-delta, star-delta, and delta-star can step voltages up or down as needed. For high loads, three-phase transformers can be connected in parallel as long as their polarities match, phase displacements are aligned, and voltage ratios are equal to prevent circulating currents.Power Amplifier

This document summarizes three types of single-phase induction motors: split-phase induction motors, capacitor-type single-phase induction motors, and shaded-pole motors. It describes the basic construction and working principles of each type of motor. Split-phase motors use an auxiliary winding to provide starting torque. Capacitor motors add a capacitor, either temporarily or permanently, to improve starting torque. Shaded-pole motors produce a rotating magnetic field through the use of shaded poles on the stator. The document provides examples of applications for each type and includes diagrams of their electrical configurations and torque-speed characteristics.F010112934

This document simulates a linear oscillating tubular motor (LOTM) using mathematical equations and computer tools. It begins by describing the components and operating principle of the LOTM, which consists of an iron bar moving inside a coil. The displacement of the iron bar causes periodic variations in the coil inductance.
The document then presents the mathematical equations that govern the LOTM's operation in terms of inductance as a function of displacement. A block diagram shows how these electrical and mechanical equations are solved using simulation. Graphical results from the simulation show how parameters like inductance, magnetic force, and speed vary over time and displacement. In conclusion, the document discusses how further optimization of the LOTM's magnetic circuit andSimulation of a linear oscillating tubular motor

This document provides lecture notes on electrical drives and traction. It discusses the basic components and advantages of electric drive systems, including their flexible control, easy starting and braking, and ability to operate in all four torque-speed quadrants. The choice of an electrical drive depends on factors like the steady-state and transient operation requirements, the power source capabilities, and cost, space, and maintenance considerations. The key elements of an electric drive system are the mechanical load, motor, power modulator, and feedback and control unit. DC, induction, and synchronous motors are covered in the lecture, along with their speed control methods and applications to traction systems.Model que for Electric Drive

The Pala kings were people-protectors. In fact, Gopal was elected to the throne only to end Matsya Nyaya. Bhagalpur Abhiledh states that Dharmapala imposed only fair taxes on the people. Rampala abolished the unjust taxes imposed by Bhima. The Pala rulers were lovers of learning. Vikramshila University was established by Dharmapala. He opened 50 other learning centers. A famous Buddhist scholar named Haribhadra was to be present in his court. Devpala appointed another Buddhist scholar named Veerdeva as the vice president of Nalanda Vihar. Among other scholars of this period, Sandhyakar Nandi, Chakrapani Dutta and Vajradatta are especially famous. Sandhyakar Nandi wrote the famous poem of this period 'Ramcharit'.
