## Sample 1: 12-Pulse Thyristor Rectifier Circuit

Power circuit diagram sample: This sample shows a simple twelve-pulse thyristor rectifier circuit diagram with YD11 transformer connected. The rectifier included in this circuit is an electrical device used to convert AC to DC. This means converting a periodically varying current into a current flowing strictly in one direction. A twelve-pulse bridge connection consists of two six-pulse bridge circuits and is often used with rectifiers. These two six-pulse bridges are connected in series.

## Sample 2: AC Chopper Electrical Circuit

Power circuit diagram sample: This sample shows an AC chopper electrical circuit. An AC chopper is a static power electronics device used as an AC converter. It is a highly demanded device owing to the fact that the current supplied to the load is often discontinuous.

## Sample 3: Alternator Circuit Diagram

Power circuit Diagram sample: This sample shows an alternator circuit diagram. The alternating current generating systems have been known since the 1830s when the magnetic induction of electric current was discovered. An alternator is an electric generator that converts mechanical energy to electrical energy in the form of AC. The modern alternators are used in automobiles to charge a battery and to power the electrical system at the running engine.

## Sample 4: DC Machine Connections

Power circuit diagram sample: This sample shows the connector types for a DC machine. You can observe in detail how a field coil may be connected. There are three alternatives of electrical connections between the stator and rotor in DC electric machines (motors or generators): in shunt or parallel, in series, and in the compound. The compound connections join the previous two types in different combinations. Each of these types offers the unique characteristics of speed and torque.

## Sample 5: DC Motor with the Field and Armature Circuits

Power circuit diagram sample: This sample shows a simple DC motor with two circuits — field and armature. The field circuit is always a constant current. It flows in the excitation winding of a rotating electric machine and creates a magnetic field. In this case, the rotor winding acts as an excitation winding. The armature is the winding of an electric machine that carries an alternating current. It is a conductor or a conductive coil.

## Sample 6: Double Fed Asynchronous Machine

Power circuit diagram sample: This sample shows a double-fed asynchronous machine. It is a type of electric motor or electric generator. The double-fed machine is similar to AC electrical generator but has some additional features. It runs at higher or lower speeds than its natural synchronous speed.

## Sample 7: Double Fed Induction Generator Connected to a Wind Turbine

Power circuit diagram sample: This sample shows a Dual Powered Induction Generator (DFIG) connected to a wind turbine. The generators of this type are most commonly used, according to statistics about 80% of all worldwide used generators are DFIG. DFIG-based wind turbines possess the flexibility and ability to control active and reactive power. DFIG contains an induction generator with a multiphase wound rotor and a multiphase slip ring. The rotor windings are connected to the converter via slip rings and the stator ones are connected to the grid. The converter controls both the rotor and grid currents, and the stator's power fed to the grid. It controls the rotor field current frequency and the generator rotor speed.
