Introduction to CC CV Power Supply
A Constant - Current (CC) and Constant - Voltage (CV) power supply is a type of power supply that can operate in two main modes. In the constant - current mode, the power supply maintains a stable output current regardless of the load resistance changes within a certain range. This is crucial in applications such as battery charging, where a specific current is required to charge the battery safely and efficiently. In the constant - voltage mode, the power supply provides a fixed output voltage, and the current adjusts according to the load. This is widely used in electronic devices that require a stable voltage to function properly, like integrated circuits and display panels.
CC CV power supplies are essential in various industries, including electronics manufacturing, telecommunications, and renewable energy. They ensure the reliable operation of electrical equipment and help to prevent damage caused by over - current or over - voltage.
