VT3045C-M3/4W

General Introduction

The VT3045C-M3/4W is a three phase rectifier array designed by Vicor that offers steady and reliable performance for various applications. It can be used for the conversion of rectified AC to DC voltage or voltage step-down applications. It is available in a variety of outputs from 8 to 16 A with a high peak current (2.2 x IOUT) and a 0.5 A minimum power range. The rectifier array consists of three Schottky diodes housed in a metal package, each with its own associated capacitors.

Working Principle

The VT3045C-M3/4W rectifier array works in a 3-phase bridge topology. All three phases of the input alternating current (AC) are connected to the three Schottky diodes in the array. As the AC power cycles through each of the three phases, the diodes turn “on” and “off” very quickly in a precise pattern on each cycle. This allows the alternating current to be converted to direct current.The efficiencies of rectification are improved by the use of snubber circuits connected to each diode or the common node terminal of the VT3045C-M3/4W. This reduces the stored energy in the diodes which improves the diodes’ current handling capability. The capacitors connected to each diode filter out any noise or ripples that may be present in the DC output.

Application Field

The VT3045C-M3/4W rectifier array is designed to be used in a wide range of applications as a DC-DC converter or as an AC-DC converter. It can be used to regulate power supply voltage to a desired level by full-wave rectification. It can also be used in monopole or polyphase switchmode power supplies to provide low losses and improved power quality. The VT3045C-M3/4W can also be used in industrial DC motor control, power conditioning, and battery charging applications. It has been proven to be reliable and efficient in providing robust power conversion with minimum losses. The array also provides good noise immunity, which helps to ensure optimal power performance.

Conclusion

The VT3045C-M3/4W is an ideal solution for a wide variety of applications thanks to its high-performance, efficient design. It offers a reliable, smooth conversion of AC to DC voltage with minimal losses, noise or ripples. The snubber circuits connected to each diode help to reduce the stored energy in the diodes and ensure optimal power performance. The VT3045C-M3/4W is a great choice for industrial use, battery charging and other applications.
