IRM-20-12 Power Modules

IRM-20-12 Description

With the help of Mean-Well USA Inc.’s IRM-20-12 AC to DC power supply, you’ll be able to safely convert alternating currents into direct currents so that your electronic devices can use the direct currents. This will allow your electronic devices to function optimally. It has a voltage of 12 volts and a maximum output power of 21.6 watts that it can produce. The only output of this component has a capacity of 1.8 A amperes, which is the maximum current that may be safely carried through it. This component can generally perform in temperatures as low as -30 degrees Celsius and as high as 70 degrees Celsius.

How to convert from AC to DC?

The scientific field known as electricity centers on investigating the properties and actions exhibited by electrically charged particles as its primary topic. The phenomenon that occurs when charged particles are found on the surface of a material is known as static electricity, and scientists give it its name. Alterations to magnetic fields can give rise to electric currents, just as the movement of electrical charges can produce magnetic fields. The movement of electrical charges can also have magnetic fields. In the path that the flow of electrical current takes, it moves from higher potential to lower potential. Electricity and magnetism are linked together in some fashion or another. The study of magnetic fields in conjunction with electric fields is called electromagnetism.

Alternating Current (AC)

Alternating current is a type of electric current in which the flow of electric charge alternates direction at regular intervals (AC). It begins, let’s say, at zero, grows to a maximum, then decreases to zero, reverses direction, grows to a maximum going the other way, then decreases to zero, returns to the starting value, and continues this cycle indefinitely. Alternatively stated: It begins at zero, grows to a maximum, then decreases to zero. The time that elapses between two successive cycles in which a constant value is attained is referred to as the period. The number of cycles or periods in one second determines the frequency of an alternating current, and the amplitude is determined by the highest value found in either direction.

AC to DC conversion

After reducing the voltage, rectifiers transform alternating current into direct current (DC). It is necessary to have a full bridge rectifier to do an AC-to-DC conversion. In this particular piece of equipment, there are four diodes, all of which function in the forward bias as opposed to the reverse discrimination. Both of the circuit’s diodes become active during the positive half-cycle, whereas only one becomes active during the negative half-cycle. Rectification allows for converting alternating current (AC) supply into direct current (DC) supply. The image that may be found below illustrates a full-bridge rectifier circuit

Purifying DC waveforms

DC waveforms were formed in the phase before this one, but those waveforms did not contain any pure DC waveforms. It arrives in pulses, and the quantity varies significantly from time to time. To carry out this activity, components that go by capacitors are used. The capacitor stores energy as the input voltage rises from zero up to its maximum value. This allows the energy to be used at a later time. When the voltage in the circuit approaches zero, the stored energy in the capacitor is released. The waveforms are significantly altered, although they become much more straightforward.

Fixing up DC voltage

Using the voltage regulator IC as the final step, the DC voltage is adjusted to the required value after being converted. Our direct current (DC) supply is ultimately changed to a predetermined voltage using an integrated circuit known as the DC voltage regulators IC. For instance, the 7805 Voltage Regulator IC is utilized whenever there is a need to convert to a 5V DC source. In addition, we use a 7809 voltage regulator IC to change the supplied voltage to 9 volts DC.

Rotary Converter

A mechanical rectifier, inverter, or frequency converter is what a rotary converter ultimately boils down to being. Using mechanical energy allows for converting alternating current (AC) to direct current (DC). The rotary converter comprises two machines joined together by a single field coil and an armature that rotates around it. It is equipped with a DC generator known as a dynamo with a set of slip rings tapped into the windings of its rotor at equal intervals. A commutator is used to remove direct current from the rotor to rectify the alternating current, which is done using the commutator. Direct current is generated due to the electrified coils’ rotation, which excites the field windings that remain stationary. The rotary converter combines the functions of a dynamo and a mechanical rectifier into a single device. Because it contains AC slip rings, it can also function as an alternator.

Switched-mode power supply (SMPS)

The electronic components of a switched-mode power supply (SMPS) include a high-frequency switching device, such as a MOSFET, and a storage component, such as an inductor or capacitor, that provides power when the switching device is not conducting. These components form a sophisticated circuit that changes alternating current into direct current.
