AC DC Converters: BP5055-12 Application Field and Working Principle

AC DC Converters are power control solutions that convert AC into DC power. BP5055-12 is a type of AC DC converter that is highly reliable and efficient. It is commonly used in industrial, commercial, and residential applications.The BP5055-12 is a voltage regulator and can work with input voltages ranging from 178VDC to 350VDC. The output voltage can be accurately controlled by an external analog or digital signal. It has a maximum output current of 12A and a wide on/off ratio (up to 1000:1). The device also has overload and overvoltage protection.The BP5055-12’s main components include a bridge rectifier, an active clamp circuit, a frequency control oscillator, an error amplifier, an external MOSFET switch, and a voltage control circuit.The bridge rectifier converts the AC input voltage into DC. The active clamp circuit provides the feedback signal to the error amplifier which controls the output voltage. The frequency control oscillator provides the control frequency which is used to drive the MOSFET switch. The voltage control circuit sets the output voltage.In operation, the BP5055-12 adjusts the output voltage according to the input signal. When the input signal goes below the target voltage, the error amplifier triggers the MOSFET switch, allowing current to flow to the output terminal. When the input signal goes above the target voltage, the error amplifier turns off the MOSFET switch, preventing current from flowing to the output terminal. This creates a precise voltage control loop and ensures that the output voltage stays within the preset limits.The BP5055-12 is a highly reliable and efficient conversion device that is perfect for industrial, commercial, and residential applications. Its wide on/off ratio, precise voltage control, and overload and overvoltage protection make it suitable for various power control solutions. Its easy installation and simple operation make it ideal for a wide range of applications.
