AC DC Converters: VMS-350-12-1 Application Field and Working Principle

The VMS-350-12-1 is an alternating current (AC) to direct current (DC) converter, or AC/DC converter. This type of equipment is used in a variety of applications ranging from powering batteries to energizing rectifiers. Additionally, AC/DC converters can be used to operate electric vehicles, machine tools, lighting, and even home appliances. The nature of DC makes it compatible with these and other applications that require minimal electrical interference. Ultimately, the principal goal of using an AC/DC converter is to convert AC into DC with minimal losses.

The VMS-350-12-1 is designed for a maximum switching frequency of 350 kHz and a 12 VDC output voltage. It boasts a high efficiency of up to 94%, and it can handle input voltages of 80-265 VAC with a wide temperature range of -40°C to +85°C. It has a 12-pin PNP or 16-pin (SIP) package, and its power stage incorporates an insulated gate bipolar transistor (IGBT) structure. Additionally, in terms of physical features, the VMS-350-12-1 measures 6.37", 8.27" and 3.46", and weighs just 3.85lbs.

The VMS-350-12-1 converter has an internal forward reluctor, flux-linkage (driving energy) detector, dedicated overcurrent protection, voltage regulation (VR), current-mode control (CMC), and a temperature control circuit. This ensures a minimum of components required in the overall circuit, and also helps to simplify the device’s operation. In order to optimize the device’s efficiency, the VMS-350-12-1 also uses a multi-winding transformer to compensate the input power drawn by the converter. This helps to minimize losses from the incoming AC power supply.

To understand how the VMS-350-12-1 operates, it is important to understand the basic working principle of AC/DC converters. Its job is to take the incoming AC power and convert it to a constant DC output. This is accomplished by a process known as frequency conversion. An inverter circuit with an oscillator is used to generate a high-frequency alternating voltage, which is then converted into a direct current via a transformer. The output voltage is adjusted and filtered to provide a constant DC output.

The VMS-350-12-1 also has an adjustable soft-start feature that allows the converter to gradually increase its output voltage over a short period of time. This helps to prevent the converter from being overloaded while it is being operated. Additionally, the VMS-350-12-1 has integrated protection circuits which are designed to protect against an excessive overload, overvoltage, and short circuit conditions. Finally, the overall device is designed to meet relevant EMC standards.

The VMS-350-12-1 AC/DC converter is a robust and highly efficient device designed for a variety of applications. Its primary purpose is to convert AC to DC with minimal losses. The VMS-350-12-1’s power stage incorporates an IGBT structure and has integrated protections circuits to prevent overload, overvoltage, and short circuit conditions. Additionally, it has a multi-winding transformer to compensate the input power drawn by the converter and an adjustable soft-start feature to prevent it from being overloaded. Finally, the VMS-350-12-1 can operate in a wide range of temperatures and meets all applicable EMC standards. All of these features combined make the VMS-350-12-1 a great choice for AC/DC conversion applications.
