About constant voltage (CV) and constant current (CC) power supply

Power supply is a device that provides electric energy for the load. The power circuit is what converts input electric energy into the desired form and outputs what called "power circuit". Power circuit can be roughly divided "constant voltage power supply" and "constant current power supply".

Constant voltage power supply is power circuit that controls output voltage at a constant level. It always provides a constant voltage regardless of the load and is widely used as power supply for electronic circuits.

Constant current power supply is a power supply circuit that controls the output current at a constant level. A constant current power supply is used to power LED lighting and charge rechargeable batteries.

The overview of Switching power supply

Switching power supply is a device which use modern power electronics technology to control time ratio of switching tube open and off and maintain a stable output voltage of power supply, switching power supply is generally composed of IC and MOSFET which is controlled through pulse width modulation (PWM) compared with linear power. The cost of switching power supply increases with the increase of output power, but the growth rate is different. Linear power cost is higher than switching power supply at a certain output power point, which is called cost reversal point. With the development and innovation of power electronics technology and switching power supply technology constantly innovating, this cost reversal point is increasingly moving to low output power end, which provides a broad development space for switching power supply.
Switching power high-frequency is the direction of its development, high-frequency will make switching power miniaturization and make switching power into a wider range of applications, especially in the field of high-tech applications, promoting high-tech products miniaturization and portability. In addition, the development and application of switching power supply are of great significance in energy saving, resource saving and environmental protection.

The main power electronic devices used in switching power supply are diode, IGBT and MOSFET.
SCR has a small number of applications in switching power supply inputting rectifier circuit and soft start circuit, GTR is difficult to drive with low switching frequency and gradually replaced by IGBT and MOSFET.

Three conditions of switching power supply
1. Switching: power electronic devices work in the switching state rather than linear state
2. High frequency: power electronic devices work at high frequency rather than low frequency close to power frequency
3. DC: switching power supply output is DC rather than AC
