AC DC converters are electronic components that allow an alternating current (AC) power supply to be converted into a direct current (DC) power supply. This conversion provides a source of power for DC applications such as welding, computer DC motors, printing presses, and more. The MB65S15K is a typical example of an AC-DC converter.

The MB65S15K is a non-isolated full-bridge step-down converter designed to convert a higher voltage AC power to a lower voltage single-output DC power. The device also contains a built-in switching circuit that works in conduction with a paired control IC to build a complete switching power supply system. In addition, the device has a wide range of over-current, over-voltage, and over-temperature protections.

The working principle of the MB65S15K is simple and efficient. The high-voltage AC power source is fed into a full-bridge rectifier, which then rectifies the current, producing a higher DC voltage on the output side. The switching control circuit then switches the rectified current repeatedly to output step-down regulated DC voltage. The switch takes up the output voltage ripple, so the output voltage can reach a steady state. The control IC can adjust the duty cycle to maintain the required output voltage, which allows the power supply to be regulated in either step-down or adjustable modes.

The MB65S15K can be used for a wide range of AC-DC power applications, including welding, DC motors, inverters, elevators, power tools, machine tools, and more. The device is extremely reliable for long-term use and has a high degree of accuracy in its output voltage control. With its built-in overcurrent, overvoltage, and over-temperature protection, the MB65S15K provides a safe and efficient DC power conversion option.
