AC DC Converters: PS-25-5 Application Field and Working Principle

AC/DC converters, also known as rectifiers, are the most widely used power electronics devices with an efficient capability to convert AC/DC power. The acronym for AC/DC is alternating current/direct current which describes the flow of current. AC/DC converters come in all shapes and sizes and have a wide range of applications. One such converter is the PS-25-5 which is one of the most popular AC/DC converters used in commercial, industrial, and automotive applications. In this article, we shall discuss the PS-25-5 application field and working principle.The PS-25-5 AC/DC converter is a high-efficiency, low-ripple, low-cost, compact, and high-density power device. It has an output voltage range of 5V-25V, an output current of 0.2A to 5A, and an operating temperature range of -30°C to 85°C. The device is ideal for use in various applications such as Battery Chargers, Uninterruptible Power Supplies (UPS), Mobile Communications, Automotive Electronics, LED Lighting, Industrial AC/DC, and Server power.The PS-25-5 AC/DC converter operates on conventional switching topologies such as Buck, Boost, and Flyback converters. The switching topologies have versatile design architectures and support a wide array of circuit design configurations, providing a standard power solution for commercial, industrial, and automotive applications. The Buck converter works on the principle of step-down topology and is one of the most commonly used AC/DC switching topologies. The DC voltage output is generated by the process of bucking or step-down the voltage of a higher voltage to a lower output voltage. The Boost converter, on the other hand, works on the principle of step-up topology and generates a higher output voltage than the input voltage. It is typically used in applications where the input voltage is lower than the desired output voltage. The Flyback converter works on the principle of keeping the power in the coil while the current through it reverses direction. The PS-25-5 AC/DC converter consists of a PWM control circuit, switching element, power inductor, min Inter-winding transformer, and output diode. The PWM control circuit generates a switching frequency signal to control the conduction and commutation of the switching element. The switching element consists of two power MOSFETs and operates in the on and off state according to the PWM control signal. The power inductor is used to reduce the ripple of the output voltage and also provide a filter function. The min Inter-winding transformer provides galvanic isolation between input and output, reducing the output voltage ripple. The output diode is used to rectify the output voltage and provide the AC/DC conversion.In conclusion, the PS-25-5 AC/DC converter is a reliable, compact, and high-efficiency power device suitable for battery chargers, UPS, mobile communications, automotive electronics, LED lighting, industrial AC/DC, and server power applications. It operates on conventional switching topologies such as Buck, Boost, and Flyback converters and consists of a PWM control circuit, switching element, power inductor, min Inter-winding transformer, and output diode.
