A rectifier is a device specifically designed to convert alternating current (AC) into direct current (DC). This process is essential in various applications where DC is required for powering electrical devices, such as in power supplies for electronic circuits.

The function of the rectifier involves allowing current to flow only in one direction, effectively blocking the reverse flow of AC, which can be achieved through semiconductor devices like diodes. As a result, the output of a rectifier is a pulsating direct current, which can be smoothed out with additional components like filters to produce a more stable DC output.

Understanding the role of a rectifier is crucial for anyone involved in beauty therapy equipment that relies on electronic components, as it ensures that devices operate safely and effectively with the appropriate type of electrical current.
