AC/DC converters such as the VMS-225-24-1 are devices used to convert alternating current (AC) to direct current (DC). The name “AC/DC converter” actually encompasses several different types of converters, such as modulated inverters, bidirectional converters, three-phase rectifiers and low-frequency converters. This article will explain the application field and working principle of the VMS-225-24-1.

The VMS-225-24-1 is a type of high-frequency AC/DC converter, also known as a Pulse-Width Modulation (PWM) inverter. It is specifically designed to convert single-phase, high-voltage AC utility power to low-voltage three-phase DC power for use in industrial automation applications. It is a highly efficient inverter, as it is capable of converting AC power with an efficiency rate of up to 98% - far higher than traditional AC/DC converters.

The working principle of the VMS-225-24-1 involves two stages: first, the method of pulse-width modulation is used to convert the AC voltage to a DC voltage; then, an IGBT-based, three-level topology is used to convert the DC voltage to a three-phase voltage with lower voltage across each phase. In order to achieve the highest efficiency, the converter also includes an integrated soft-switching technology to reduce switching losses.

The VMS-225-24-1 is a highly versatile single-phase, high-voltage AC to low-voltage three-phase DC converter that is suitable for a wide range of industrial automation applications. These include CNC lathes, robotic arms, pick-and-place machines, industrial sewing machines, and other motor-driven applications where low-voltage three-phase DC power is required. The high efficiency of the VMS-225-24-1 ensures that the energy conversion process is as efficient as possible, thus reducing energy costs.

In summary, the VMS-225-24-1 is a type of high-frequency AC/DC converter specifically designed to convert single-phase, high-voltage AC utility power to low-voltage three-phase DC power for industrial automation applications. It uses a method of PWM to convert the AC voltage to a DC voltage, and then an IGBT-based, three-level topology to convert the DC voltage to a lower-voltage three-phase voltage. The VMS-225-24-1 is highly efficient and versatile, allowing it to be used in a wide range of applications where low-voltage three-phase DC power is required.
