AC DC converters, such as VSBU-120-T125A, are widely used power conversion devices that are capable of converting alternating current (AC) into direct current (DC). The VSBU-120-T125A is typically used in applications ranging from aerospace, automotive, railway, industrial automation, medical, telecommunications, lighting, and renewable energy. The majority of commercial AC DC converter designs are made for use in stationary applications, therefore, they are not suitable for mobile applications.

The VSBU-120-T125A is an AC DC converter designed specifically for mobile applications that require high performance and reliability. This converter operates in a switched mode, meaning that it switches on and off at high frequency to transfer power from the AC source to the DC. The VSBU-120-T125A is designed to operate over a wide AC input voltage range of 170 to 250V cases, making it suitable for applications where the AC input voltage varies widely. It also features a maximum conversion efficiency of up to 96%, making it one of the most efficient AC DC converters on the market.

The working principle of the VSBU-120-T125A is rooted in the basic operation of a DC-DC converter circuit. Essentially, it takes AC power input, and then rectifies it to form DC power. This is done by first rectifying the AC signal via a diode bridge to form a pulsed direct current (Pulse DC). This Pulse DC is then smoothed out by an inductor or capacitor, and then fed into a switch to determine the amount of voltage and current that is delivered to the load.

The modified square wave that is then output from the switch is then fed through another filter to ensure the output voltage and current remain stable. Finally, the output voltage from the switch is fed through a feedback circuit that monitors and maintains a predetermined output voltage and current. In modern AC DC converters, this feedback circuit often has multiple stages and uses pulse-width modulation to ensure accurate output voltage and current measurements.

The VSBU-120-T125A works by taking the AC input, rectifying it to form a constant pulsed DC, and then using a switch to convert the pulsed DC into a modified square wave. This modified square wave is then fed through a filter and adjusts the output voltage or current as required. The advantage of the VSBU-120-T125A over other AC DC converters is the efficiency rating of up to 96% and its wide AC input voltage range of 170 to 250V.

In conclusion, the VSBU-120-T125A is an AC DC converter designed for mobile applications, and its wide AC input voltage range and high efficiency make it a valuable tool for a variety of applications ranging from aerospace to renewable energy. Its working principle is rooted in the basic operation of a DC-DC converter circuit, with the output modified square wave being fed through a filter and the output voltage and current being maintained via a feedback circuit.
