RECTIFIERS ABSTRACT A rectifier is an electrical device that converts alternating current (AC) to direct current (DC) and the process is known as rectification. Rectifiers have many uses including as components of power supplies and as detectors of radio signals. Rectifiers may be made of solid state diodes, vacuum tube diodes, mercury arc valves, and other components. When only one diode is used to rectify AC (by blocking the negative or positive portion of the waveform), the difference between...

Project Report on Full Wave Rectifier

INTRODUCTION A full wave rectifier is a device which is used to rectify all the alternating current components in an alternating supply and make it purely a direct current. The two alternating halves of an alternation current are rectified in a full wave rectifier which is an advantage over a half wave rectifier. Most of electronic devices cannot withstand very high voltage or alternating current due to its intense high power. The use of batteries in all devices is not practical as their replacement...

stabilization. Figures 1 and 2 show the simplest rectifier circuits. In these basic configurations the peak voltage across the load is equal to the peak value of the AC voltage supplied by the transformer’s secondary winding. For most applications the output ripple produced by these circuits is too high. However, for some applications - driving small motors or lamps, for example - they are satisfactory. If a filter capacitor is added after the rectifier diodes the output voltage waveform is improved...

Diode Applications

7. Tuning Let us examine each of these applications with some considerable detail. RECTIFICATION: The process of converting AC into DC is called rectification. Diodes can be used as half wave rectifiers and full wave rectifiers. Half Wave Rectifier: Circuit Diagram: . In the Half wave rectifier circuit shown above the transformer serves two purposes. 1. It can be used to obtain the desired level of dc voltage (using step up or step down transformers). 2. It provides isolation from the...

circuit this way. It appeared that the 110 ohm resistor was in series with the parallel combination of the 330nF capacitor and the 1Mohm resistor. That was a little confusing because I had assumed that the capacitor would be in series after the bridge rectifier as in a capacitor-input filter. After a few attempts to sketch the rest of the diagram, we decided to use Multisim. Multisim was a very useful tool. It allowed us to use all of the components on the circuit, and, through trial and error, create a...

Disadvantage Of Hybrid Cars

Figure 3 Voltage Regulator IRF840 2.2.3 RECTIFIER A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification. Physically, rectifiers take a number of forms, including vacuum tube diodes, mercury-arc valves, copper and selenium oxide rectifiers, semiconductor diodes, silicon-controlled rectifiers and other silicon-based semiconductor switches...
