What device converts AC to DC?

The device that converts alternating current (AC) to direct current (DC) is a rectifier. A rectifier functions by allowing only one direction of current to pass through it, effectively "clipping" the AC waveform so that only the positive or negative portions are utilized, depending on the type of rectifier configuration used: half-wave or full-wave.

In practical applications, rectifiers are commonly found in power supplies, where they convert the AC from the mains into DC suitable for powering electronic devices. The rectification process is crucial for many applications, especially in circuits that require a stable DC voltage.

Understanding the function of a rectifier is important for anyone involved in refrigeration systems, as many components, such as electronic control circuits and sensors, require DC power to operate effectively.
