AC DC Converters: PBW50F-5-G Application Field and Working Principle

The PBW50F-5-G power supply is a state-of-art AC/DC converter offering multiple advantages over traditional AC/DC converters such as improved efficiency, fast transient response, good power factor, and reduced total harmonic distortion. It is purely digital and suitable for various applications including industrial, electrical, military, marine, medical, and other general applications. This article provides an introduction to the application area of the PBW50F-5-G and its working principle.

Application Field

The PBW50F-5-G power supply is capable of supplying regulated DC power in the range of 9 - 56V with adjustable output voltage and current or fixed output voltage of 24Vdc/5A. It is suitable for small electronic devices such as laptops, PDAs, phones, and LED lighting, and for various automation control systems and factory automation applications. It is also suitable for medical equipment, military on-board applications, and other general electronic equipment. With its dual-mode power supply technology, it is capable of supplying both resistive and non-resistive loads.

Working Principle

The PBW50F-5-G power supply consists of three main components—the input AC voltage, the power factor correction circuit, and the output DC voltage. Its working principle is simple and efficient. When AC power is supplied, the power factor correction circuit is activated to reduce the power consumption by the AC/DC converter.The input AC voltage is first rectified by a diode bridge circuit. The rectified current then passes through a power factor correction circuit, which consists of a combination of passive components such as capacitors and inductors. The PFC circuit reduces the total harmonic distortion (THD) of the output voltage, making it more stable.The power factor corrected voltage is then converted into DC voltage by an integrated switching DC/DC converter, where the voltage is regulated and finally output as DC power. This output DC voltage is adjustable by programming the switching DC/DC converter control register.

Conclusion

The PBW50F-5-G power supply is a compact, efficient, and reliable power supply offering higher efficiency and improved performance in various demanding applications. Its dual-mode technology and PFC circuit make it suitable for supplying loads of different types. With its adjustable output voltage, it is ideal for supplying various electrical equipment without any additional hardware.
