CU15-13

AC/DC converters are common electrical components that are used to convert electrical energy from alternating current to direct current. The CU15-13 AC/DC converter is one of the most widely used converters today due to its simple structure, high efficiency, and wide range of applications. This article will discuss the application field and working principle of the CU15-13 AC/DC converter.

Application Field

The CU15-13 AC/DC converter can be used in a variety of applications. It is most commonly used for on-board battery charging, such as in hybrid and electric vehicles, as well as for power supplies for electronic devices. It can also be used for low power, low voltage applications, such as for computer motherboards power, or for laptop power adaptors. The CU15-13 converter is also used in industrial applications, such as for motor drives, and in control systems, such as for AC and DC induction motor control.

Working Principle

The CU15-13 AC/DC converter is a non-isolated, linear switching regulator featuring high efficiency and low operating losses. The working principle of the converter is based on a push-pull topology, which means that it consists of an upper and lower converter. The upper converter is responsible for converting the alternating current to a constant direct current, while the lower converter is responsible for controlling the output voltage.

The input voltage is first rectified by the bridge rectifier and then fed to the inductor. The inductor\'s magnetic field is then used to store energy, which is then released when the switch is opened. The switch is controlled by the control IC, which ensures the output voltage is kept constant. The rectified voltage is then filtered by the capacitor, which further smoothes the output waveform.

The CU15-13 AC/DC converter is a reliable and efficient way to convert alternating current to direct current. Its simple structure, high efficiency, and wide range of applications make it one of the most popular converters used today.
