The rated output power is 120V with a maximum instantaneous capacity up to 2kW. The peak current allowed is 15A. The converter has a wide input range, adaptable to various control methods, and a switching frequency up to 40kHz for noise reduction and simplified design.

Applications of VI-B63-MW-F3 Converter

VI-B63-MW-F3 converters are used in a wide range of applications where high-voltage and high-current levels are needed. Examples include power generation, data center, industrial, automotive, aircraft and other aerospace applications. In these applications, the converter is used to provide regulated and conditioned power for the main equipment. It can also be used to support other auxiliary loads, such as LED lighting, motor drives, and other equipment that require steady power.

VI-B63-MW-F3 Working Principle

The VI-B63-MW-F3 power converter follows the typical buck converter architecture, with a series-connected high-frequency voltage-regulating pulse-width modulated (PWM) switching element. The input voltage is applied to the switching element that drives a high-frequency transformer. This transformer block transfers the input voltage to the output circuit. Here, the output voltage is rectified and regulated to the desired voltage level through feedback pulses driven by the PWM switching circuitry.

Operating the converter at high frequency induces higher currents during the switching intervals. To absorb this energy, an output filter capacitor may be used for capacitor filtering. This capacitor also provides energy storage, which helps to maintain the regulated output under load variations, thus ensuring the converter’s stability over time. At the same time, this capacitor smoothens the current ripple for improved operation.

Summary

The VI-B63-MW-F3 is a switching-mode DC-DC converter of the buck converter type, capable of supporting high-current and high-voltage levels. The converter has a wide input voltage range and its switching frequency can be adjusted to reduce noise and simplify design. The VI-B63-MW-F3 is used in power generation, data center, industrial, automotive, and aerospace applications, to provide regulated power for the main equipment or other auxiliary loads. The working principle of the converter is based on the pulse-width modulated switching architecture, with the input voltage applied to the switching element and then transferred to the output circuit through a transformer. The output filter capacitor helps to absorb high switching currents and maintain the output voltage stability over time.
