AC DC Converters are electrical devices that convert alternating current (AC) into direct current (DC). The VGS-75-15 is a type of AC DC Converter which provides a reliable power conversion solution for a number of industrial applications. This article will discuss the application field and working principle of the VGS-75-15.

Application Field

The VGS-75-15 is a powerhouse AC DC Converter that is designed for rigorous and large power conversion and is suitable for a variety of industrial applications. Its versatile nature allows it to be used for a range of applications such as commercial, automotive, HVAC, transportation, lighting, defense, industrial, medical and any other application where an efficient power conversion is required. In fact, the VGS-75-15 has been designed to meet the most demanding industrial requirements.

The VGS-75-15 offers output flexibility with an adjustable output voltage range. It is incredibly lightweight and compact, making it perfect for restricted space conditions where a robust and efficient power converter is needed. It is designed to address a multitude of power problems in harsh environments, and is rated to withstand shock and vibration levels which are compatible with MIL-STD-810 standards. This versatile power converter also features built-in protection circuitry for short circuit, overload, over voltage, and over temperature respectively.

Working Principle

The VGS-75-15 utilizes a Pulse Width Modulation (PWM) to convert AC power into DC power. PWM is a process where certain parameters of a switching circuit (constant on-time, off-time, etc.) are varied with a given frequency to drive the power converter. The output voltage of the converter is also adjustable and is controlled by the input voltage, on/off signals, and modulation controls. In the VGS-75-15, the PWM operates with a maximum switching frequency of 200 kHz, allowing the power converter to achieve high efficiency and high power factor conversions.

The PWM used by the VGS-75-15 also takes into account several other important aspects of power conversion such as power factor, output ripple, transient response, etc. In order to ensure a smooth and efficient output, the PWM has built-in features that ensure over-current, short-circuit, and over-temperature protection. The PWM also enables Power Factor Correction (PFC), a method which helps to attenuate the harmonic currents that can otherwise shoot up harmonics into the mains voltage, leading to power quality issues.

The VGS-75-15 is designed with an efficient thermal management system that not only ensures cooling of the converter, but also allows it to achieve high power efficiency and reliability. This thermal management system uses a simple but effective air-flow, while utilizing built-in heatsinks to dissipate heat away from the components of the converter.

The VGS-75-15 AC DC Converter is a great way to incorporate reliable power conversion in a variety of industrial applications. With its adjustable output voltage range and built-in protection functions, the converter is highly reliable and well-suited for mission-critical applications. Its efficient thermal management system ensures high power efficiency, long-term reliability, and overall longevity of the power converter.
