V375A15C600AL Vicor 375V Input 15V Output 600W DC-DC Converter Module
The V375A15C600AL, a cornerstone of the Vicor Maxi family, delivers high-density 15V DC power from a high-voltage 375V nominal bus. This 600W DC-DC converter is engineered for industrial and telecommunication systems requiring isolated, regulated power in a low-profile package. By utilizing ZCS/ZVS switching technology, it maximizes efficiency while significantly reducing electromagnetic interference, making it an ideal choice for dense Distributed Power Architectures. For systems requiring higher voltage isolation, this module provides 3,000 Vrms isolation from input to output.
375V (250–425V) | 15V | 600W | 87.5% Efficiency
- Thermal Efficiency: Integrated baseplate allows for direct heatsink attachment, ensuring reliable operation under high-load conditions.
- Design Flexibility: Programmable output voltage (10% to 110%) enables precise tuning for specialized logic or battery charging applications.
How does the V375A15C600AL handle high-power dissipation in space-constrained enclosures? It relies on a high-conductivity baseplate design that facilitates rapid heat transfer to external cooling systems, maintaining a high power-to-weight ratio. For 375V DC bus systems prioritizing thermal margin, this 600W module is the optimal choice.
Application Scenarios & Value
Streamlining Power Delivery in High-Voltage DC Bus Architectures
The V375A15C600AL is specifically designed to bridge the gap between high-voltage DC rectification stages and low-voltage peripheral requirements. In a typical Uninterruptible Power Supply (UPS) or a Solar Inverter, the system operates on a high-voltage internal bus. This module converts that 375V potential into a stable 15V supply for cooling fans, control circuitry, and HMI interfaces. The 600W output capacity allows a single module to power multiple subsystems, reducing the overall component count and increasing system MTBF.
A significant challenge in industrial automation is managing the inrush current and voltage spikes associated with motor drive startups. The V375A15C600AL addresses this through its robust 250V to 425V wide input range, which provides a safety buffer against line transients. This prevents logic-side brownouts during heavy inductive load switching. While this model provides high-power 15V output, systems requiring standard industrial 24V rails may consider the related V375A24C600AL for direct compatibility.
Integrating this module also simplifies compliance with global safety standards. With its UL/CSA/EN 60950-1 certifications, engineers can accelerate the certification process for the entire end-equipment. For further insights on integrating power modules into complex systems, engineers often refer to IGBT Modules and Power Efficiency guidelines.

Technical Deep Dive
Advanced ZCS/ZVS Switching for Minimal EMI and High Density
The V375A15C600AL utilizes Zero Current Switching (ZCS) and Zero Voltage Switching (ZVS), a sophisticated power conversion topology that virtually eliminates traditional switching losses. Think of standard power switching as attempting to close a door against a heavy wind—it requires force and generates noise (heat and EMI). ZCS/ZVS is like waiting for the wind to stop for a split second before moving the door; it is nearly frictionless. This allows the Vicor module to operate at high frequencies without the thermal penalties typically seen in hard-switching converters.
This high-frequency operation is what enables the Maxi module's 600W output in such a compact form factor. By shrinking the size of passive components like inductors and capacitors, Vicor achieves a power density that is essential for modern 800V platform auxiliary systems and high-density computing. Furthermore, the 15V output is precisely regulated via a remote sense feature, ensuring that voltage drops across long PCB traces are compensated for, maintaining 15V exactly at the load.
FAQ
How does the Rth(j-c) of this Maxi module impact heatsink selection for 600W loads?
With a low internal thermal resistance, the V375A15C600AL efficiently moves heat to its baseplate. When running at a full 600W, engineers must select a heatsink that accounts for the 87.5% efficiency, meaning approximately 75W of heat must be dissipated. Using high-performance thermal interface materials is critical to maintaining a baseplate temperature below the maximum rated 100°C.
Can the V375A15C600AL be paralleled for higher power requirements?
Yes, the module supports N+1 redundancy and power expansion. Because it uses a proprietary control architecture, multiple units can be paralleled to share current accurately without complex external balancing circuitry. This is a common requirement in fault-tolerant UPS (Uninterruptible Power Supply) systems where uptime is the primary metric.
What are the primary benefits of the 375V input range for global applications?
What is the primary benefit of its 375V input? It allows the module to operate directly from rectified 200-240V AC lines or specialized 384V DC high-voltage distribution systems used in modern data centers. This versatility eliminates the need for intermediate step-down stages, increasing overall system efficiency.
