20A High-Power Synchronous Rectifier Buck Constant Voltage Constant Current Power Supply Module Charging

Brief Introduction of Synchronous Rectification Technology:

Synchronous Rectification Is a New Technology That Uses Special Power MOSFETs with Extremely Low on-State Resistance to Replace Rectifier Diode to Reduce Rectification Loss. It Can Greatly Improve the Efficiency of the DC/DC Converter and There Is No Dead-Zone Voltage Caused by the Barrier Voltage. Power MOSFETs Are Voltage-Controlled Devices, and Their Volt-Ampere Characteristics Are Linearly Related When Conducting. When Power Mosfets Are Used as Rectifiers, It Is Required That the Gate Voltage Must Be Synchronized with the Phase of the Rectified Voltage to Complete the Rectification Function, So It Is Called Synchronous Rectification. Synchronous Rectification Technology Greatly Reduces the Rectification Loss of the Output Terminal of the Switching Power Supply, Thus Improving the Conversion Efficiency and Reducing the Heating of the Power Supply Itself.

Output Current Regulation Method:

1. Adjust the CV Potentiometer and Set the Output Voltage to the Voltage Value You Need According to Your Load Requirements.

2. Set the CC Potentiometer for about 30 Turns Counterclockwise (That Is, Set the Output Current to Small), Connect the Led, and Adjust the CC Potentiometer to the Current You Need. If the Battery Is Used for Charging, after the Battery Is Discharged, It Will Be Connected to the Output and CC Will Be Adjusted to the Current You Need. (When Charging, You Must Use the Battery That Has Been Discharged to Adjust It Accurately, because the More Power the Battery Has Left, the Smaller the Charging Current.)
