An AC DC converter, otherwise known as a rectifier, is a device that converts alternating current (AC) power into a form of direct current (DC) power. The VMS-81-24 is a type of AC DC converter, known specifically as a switching type converter. It is used mainly in adjustable and fixed DC power supply applications such as telecommunications, data processing, computers, and industrial control systems.

The VMS-81-24 is a highly efficient AC DC converter that is characterized by fast switching, low voltage levels, and superior power efficiency. It utilizes unique switch-mode techniques and switching frequencies of up to 50 kHz to minimize power losses and enable high-efficiency, high-power operation.

The VMS-81-24 consists of an input rectifier, a DC output filter, a control unit, and a power-stage. The input rectifier is a full bridge diode circuit that converts AC mains voltage into DC voltage, which is then filtered by the DC output filter. The control unit consists of a series of MOSFETs (metal-oxide-semiconductor field-effect transistors) that act as switches in order to regulate the power-stage. The power-stage is a transformer-based circuit that produces a constant, adjustable output voltage from the filtered DC voltage.

The VMS-81-24 works by first converting the AC mains voltage into DC voltage using the rectifier. This filtered DC voltage then passes through the control unit, which controls the switching of the MOSFETs. The MOSFETs, either in the on or off state, allow or prevent current from passing through the power-stage. The power-stage then produces an adjustable output voltage. This adjustable output voltage is then passed through the DC output filter to reduce any voltage ripple before being delivered to its intended destination.

Overall, the VMS-81-24 switching type converter is an excellent choice for many AC DC conversion applications, providing high efficiency, fast switching, low voltage levels, superior power efficiency, and the ability to adjust the output voltage. It is an excellent choice for applications such as telecommunications, data processing, computers, and industrial control systems.
