Diode rectifier app
Apart from normal dc supplies, they can be used as current sources, as indirect voltage measurements, for reading line frequencies, for frequency doubling non sinusoidal waveform such as triangles, squares, rectangles.
To understand the diode rectifier application, let’s understand the basic meaning of the terms ‘diode’ and ‘rectifier’ given as follows:
Diode: semiconductor diode is a two-terminal electronic component with a pn connection.Rectifier: an electronic device that converts alternating current (ac) into direct current (dc) by letting current flow through only one direction.
To use the diode as a rectifier, we must block the flow of electric current in one direction, i.e in the forward direction and to block in reverse direction which is done by bias (applying dc voltage on electronic device for correct operation).
The application of the diode rectifier: the main application of the rectifier is the alternating current (AC) to direct the current (dc) conversion as said before, the apprenticeship used in various devices as follows:
- The rectifiers are also used for the detection of amplitude-modulated radio signals.
- Rectifiers supply polarized voltage for welding.
We find the rectifier diode in all the equipment that requires the conversion of ac to dc in economical i.e, mobile charger (charger circuit mobile), motorcycle filling system.All power supplies convert the diode ac coding to dc using diodes.
Example : all your mobile phone chargers
A rectifier is an electrical device that converts alternating current (AC) into direct current (dc), a process known as rectification. rectifiers have many uses included as electrical supply components and as amplitude modulation detectors (envelope detectors) of radio signals. rectifiers are most often made using solid state diodes but other types of components can be used when very high voltages or currents are involved. when only one diode is used to fix ac, the difference between the term diode and the term rectifier is just one use. the term rectifier describes the diode used to convert ac to dc. most rectifier circuits contain a number of diodes in a special setting to more efficiently convert ac power to dc power than is possible with just one diode.
In half-wave rectification, the positive or negative half of the ac wave is passed, while the other half is blocked. because only half of the input wave reaches the output, it is only 50% efficient if used for power transfer. half-wave rectification can be achieved with a single diode in a single-phase supply .
The full wave rectifier transforms both positive and negative sections of the input waveform into a single polarity (positive or negative) at its output. by using both parts of the wave wave full wave full wave more efficiently than half wave.
