What does rectification mean and what is rectification?

Rectifier circuit Rectifier circuit.

rectifying circuit

Put the alternating current. A circuit that can be converted into direct current energy. Most rectifier circuits are made up of:

Transformer, rectifier main circuit and filter, etc. It is in a DC motor.

It has been widely used in speed regulation, excitation adjustment of generators, electrolysis, electroplating and other fields. A rectifier circuit usually consists of a main circuit, a filter, and a transformer. After the 70s of the 20th century, silicon rectifier diodes and thyristors were mostly used in the main circuit.

Compose. The filter is connected between the main circuit and the load and is used to filter out pulsation.

The AC component in the DC voltage. The transformer is set up or not on a case-by-case basis. The function of the transformer is to achieve the matching between the AC input voltage and the DC output voltage and the electrical isolation between the AC grid and the rectifier circuit (which can reduce the electrical interference and fault impact between the grid and the circuit).

According to its components, the rectifier circuit can be divided into uncontrolled rectifier circuit, semi-controlled rectifier circuit and fully controlled rectifier circuit. The latter two circuits can be divided into phased rectifier circuits and chopper rectifier circuits according to their control methods (see power electronic circuits). Due to the use of power grid commutation mode, the phased rectifier circuit does not need a special commutation circuit, so the circuit is simple, reliable and widely used.

However, when the phased rectifier circuit is used for control, the power factor.

Lower, the harmonic content of the current on the grid side is larger. Therefore, in the high-power speed regulation transmission, the use of chopping rectifier circuit can solve the problem of power factor deterioration when running at low speed.

Rectifier circuit (rectifier) is the earliest one of the power electronic circuits, which turns alternating current into direct current, which is widely used and has various circuit forms; According to the composition of the device can be divided into uncontrollable, semi-control and full control three kinds, according to the circuit structure can be divided into bridge circuit and zero circuit, according to the number of AC input phases can be divided into single-phase circuit and multi-phase circuit, according to the direction of the secondary side current of the transformer is single-phase or double-phase, and divided into single-beat circuit and double-beat circuit; The utility circuit is a combination of the structures described above.

Rectification refers to the conversion of an AC voltage into a DC voltage that ripples in one direction. In life, many occasions are inseparable from DC power supply, such as electrolysis, electroplating, DC motors, especially in electronic circuits, which need to use stable DC power supply, so it is necessary to rectify the AC power and convert it into DC power supply.

In the sense of rectification, it is to change the unstable alternating current to the stable direct current. The general rectification is divided into full-bridge rectification and half-bridge rectification, and the full-bridge rectification generally uses four diodes, most of which are boosted and need capacitors to filter to form a stable DC.

Rectification is the conversion of alternating current into direct current.

Rectification is a physical phenomenon in which the amplitude of forward and reverse currents is different under the same driving force.

1. For electronic applications, the rectifier circuit is a circuit that uses the unidirectional conductivity of the diode to change the positive and negative AC voltage into a unidirectional pulsating voltage. Under the action of the AC power supply, the rectifier diode is periodically turned on and off, so that the load gets pulsating direct current. In the positive half of the power supply, the diode is turned on, so that the current on the load is exactly the same as the shape of the voltage waveform, in the negative half of the power supply voltage, the diode is in the reverse cut-off state, and the load voltage is almost zero;

2. Half-wave rectification, half-wave rectification is the most commonly used circuit that uses the unidirectional conductivity of the diode to rectify the fierce branches, and is often used to convert alternating current.

Hello, the so-called rectification refers to the process of converting alternating current into direct current. Nowadays, the PN junction is generally used to convert the alternating current into a direct current pure side. The current switching power is also used to convert alternating current into direct current, first convert alternating current into direct current, and then use the first circuit to convert it into various required voltages, and then convert it into direct current.

Hello, glad to answer for you! Positive rectification is a negative polarity circuit when the negative poles of two rectifier diodes are connected to ground. Negative rectification is a positive polarity circuit when the positive poles of two rectifier diodes are connected to ground.

Full rectifier is a circuit that can convert AC into a single direction of current, at least by the merger of two rectifiers, one is responsible for the positive direction, the other is responsible for the reverse direction, the most classic car type of full wave rectifier circuit is a rectifier bridge composed of four sails and diodes. I hope my Sui brother will be helpful to you!

There is a mineral that has a negative rectification, does it require a negative current to recharge it?

Not really! The process of charging is a process of current moving and gathering, and the essence of the current is that a group of electrons move directionally along the wire. Although the capacitor is disconnected, when it is not fully charged, the electrons will move forward to one of the electrode plates and accumulate to become a negative plate, and the other side is a positively charged plate.

When the accumulation is full, it is equivalent to the capacitor is fully charged, and the electrons will not accumulate in a directional manner.
