What can be used to change alternating current to direct current?

A rectifier is an electrical device that transforms alternating current (AC), which flips direction on a regular basis, to direct current (DC), which travels in just one direction. The most common type of rectifier is the silicon-based semiconductor diode. Other devices such as bipolar junction transistors and metal oxide semiconductors are also used for this purpose.

The need for rectification is due to the fact that DC circuits require that electrons flow in just one direction from positive to negative. Semiconductor diodes work by transforming electricity from AC to DC; thus they must always be used in combination with other components that use electricity at different times during the cycle. For example, a flashlight requires both a semiconductor diode and a battery since it needs electricity when the circuit is closed but not when it's open. Bipolar junction transistors and field-effect transistors can be used in high-power applications where cost is less important than efficiency. Metal-oxide semiconductor field-effect transistors (MOSFETs) are particularly useful because of their small size and low voltage requirements.

In addition to diodes, other devices can be used as rectifiers including transistors, vacuum tubes, and power supplies.

What converts the wall outlet's alternating current AC into direct current DC?

A rectifier that generates DC Direct current can be produced using an alternating current generator outfitted with a device known as a "commutator." The use of a device known as a "rectifier" to convert AC to DC. Modern power supplies and converters often include multiple stages, with each stage consisting of a rectifying unit and an inductive storage element such as a capacitor or flyback diode.

The conversion process can be described by saying that the generator produces voltage pulses (waves) at a rate determined by the frequency of the alternating current it receives, and the rectifier filters these waves so that they may be used directly by the equipment being powered. A full wave rectifier will produce only positive voltage spikes while a half wave rectifier will produce both positive and negative voltage peaks. If no filtering takes place after conversion, high-frequency interference signals would be present on all parts of the circuit's line. This would be undesirable since many electronic devices are sensitive to such interference.

Filtering is usually done with either capacitors or magnetic components called inductors. Inductors tend to be more efficient than capacitors at passing low-frequency currents, so they're generally used when high efficiency is required for small amounts of energy transmission. Capacitors are less expensive than inductors and can therefore be used when large amounts of energy need to be transmitted or stored.

Can DC current be converted to AC?

A power inverter, often known as an inverter, is a piece of power electronic equipment or circuitry that converts direct current (DC) to alternating current (AC). Rectifiers are circuits that perform the reverse purpose, converting AC to DC. A power inverter can also be called a transformer, but this term is usually reserved for devices that convert higher-voltage DC into lower voltage AC.

In general, no, it cannot. An electrical circuit needs energy in order to operate, and generators take energy from any source to produce electricity. A generator cannot "make" electricity, only transform its form. There are two types of generators: mechanical and electrical.

Mechanical generators use the movement of water or wind power to drive a wheel which in turn drives an electric generator. Electrical generators use a constant speed motor coupled to a set of electromagnets to produce electricity when required. The electric power generated by electrical generators is always in the form of DC; it must then be transformed into AC before it can be used by consumers. This is done with power inverters. The type of transformation performed by a power inverter depends on the type of generator it is connected to: single-phase or three-phase.

In conclusion, yes and no. It all depends on what you mean by "convert".
