What is the purpose of converting AC voltage to DC voltage?The purpose of converting AC voltage to DC voltage is mainly to adapt to those electronic devices and circuits that require a stable DC power supply. AC voltage (AC) is a voltage that changes periodically, while DC voltage (DC) is a constant voltage. Many electronic devices, such as computers, mobile phone chargers, LED lighting, etc., require DC power to work. Here are a few common purposes and examples of converting AC voltage to DC vo
