AC DC ConvertersAC/DC converters, also known as rectifiers, are electronic devices that are used to convert alternating current (AC) to direct current (DC). AC is the type of electrical power that is commonly used in homes and businesses, while DC is the type of power used by most electronic devices. AC/DC converters are commonly used in applications where DC power is needed but only AC power is available, such as in portable electronic devices, battery chargers, and power supplies. There are many different types of AC/DC converters, including linear, switched-mode, and pulse-width-modulated (PWM) converters, which have different characteristics and are suitable for different applications.
