Introduction

DC DC converters are versatile power conversion products used to step down voltage from a higher range (input voltage) to a lower range (output voltage). The V375C8T100B2 is a high power density DC/DC converter, primarily used in distributed power architectures and telecommunication systems requiring a high voltage to current ratio while maintaining high efficiency and low standby power. It offers synchronous rectification, on/off control, and a high power density.

Application Field

The V375C8T100B2 is ideally suited to applications requiring a wide operating range, high power density, and ultra-low output ripple. It provides an excellent range for voltage conversion, from 3V to 36V input, with tight regulation. Due to its high power density, it is a good choice for applications which need a large number of power channels in a constrained environment, such as data centers, server racks, edge computing platforms, or telecommunications networks. In particular, this converter serves as a perfect solution for the power management of industrial machinery. It makes it possible to have quick switching between different power settings, which is essential for radio adapters, medical equipment, HVAC systems, and CNC machines. Its low profile 2” x 1.2” x 0.4” allows a tight fit inside equipment with limited space, and its robust cooling system ensures reliable operation even at high temperatures. It also meets the industrial safety requirements and is protected against overload, overvoltage, and short circuit.

Working Principle

The V375C8T100B2 uses a switched-mode power supply design based on the L-C resonance circuit, which is composed of an inductor (L) and one or several capacitors (C). The configuration allows for high-efficiency power conversion and is capable of providing up to 1500W of power with a peak efficiency of 94%.The current passes through an output inductor before going to the output, while the input voltage is switched between two different stages: the input transformer stage and the DC bus stage. During the input transformer stage, the current passes through the primary winding of the input transformer, generating a magnetic field which induces a voltage in the secondary winding. This secondary voltage is then filtered and rectified, providing a constant DC voltage at the input of the DC bus stage.The DC bus stage is where the output L-C circuit is regulated, and the current is transferred to the output. The output L-C resonance circuit undergoes several cycles throughout the process, where the current is alternately diverted between the inductor and the capacitors, and thus creating a sinusoidal signal which smoothes the output current and leads to high-efficiency conversion.

Conclusion

The V375C8T100B2 is a high power density DC/DC converter that is ideal for applications requiring high efficiency, high power density, and low output ripple. It offers many advantages, such as wide operating range, synchronous rectification, and on/off control. It is also compliant with various industrial safety requirements and has a robust cooling system. This converter is highly suitable for power management in industrial environments, including medical equipment, HVAC systems, radio adapters, and CNC machines.
