Core Advantages at a Glance
- Exceptional Power Density: Delivers 100 watts of output power in a compact, industry-standard full-brick package, enabling significant space savings in system design.
- High-Efficiency Operation: Utilizes a high-frequency, zero-current switching (ZCS) topology to minimize power loss, reducing heat dissipation and operational costs.
- Robust and Reliable: Fully encapsulated to withstand harsh industrial environments, offering superior protection against shock, vibration, and humidity.
- Wide Input Range: Offers a wide trim range around the nominal 24V input, providing design flexibility and resilience against input voltage fluctuations.
Technical Deep Dive: The Engineering Behind the Performance
The performance of the V24C15T100BL is not accidental; it's the result of Vicor's pioneering power conversion technology. At its heart is a Zero-Current Switching (ZCS) forward converter topology. Unlike conventional hard-switched PWM converters that suffer from high Switching Loss, ZCS activates the power MOSFETs precisely when the current through them is zero. This elegant solution drastically reduces wasted energy, which translates directly into higher efficiency and lower operating temperatures. For the system designer, this means a smaller heatsink, improved system reliability, and a significantly quieter EMI signature, simplifying the design of input filters and overall system compliance.
Furthermore, the module's mechanical design is integral to its performance. The thermally conductive encapsulant and metal baseplate create an optimized path for heat extraction. This focus on Thermal Management ensures that the Vicor V24C15T100BL can deliver its full rated power across a wide ambient temperature range, a critical requirement for fan-less systems or equipment deployed in uncontrolled environments.

Frequently Asked Engineering Questions
Q1: What are the best practices for thermal management with this module?
A: Achieving optimal performance requires a low-impedance thermal path. The module's baseplate should be mounted to a clean, flat heatsink or chassis surface using a high-quality thermal interface material (TIM). Ensure proper torque is applied to the mounting screws to minimize contact resistance. The required heatsink size depends on the load and ambient airflow; our experts can help with thermal modeling for your specific application. Understanding the fundamentals is key to unlocking thermal performance.
Q2: Can I parallel these modules to achieve a higher power output or N+1 redundancy?
A: Absolutely. Vicor Maxi modules are designed for easy paralleling. By simply connecting the "PC" (Parallel Control) pins of two or more V24C15T100BL modules, they will automatically engage in active current sharing. This feature enables scalable power solutions and the design of highly reliable, fault-tolerant systems with minimal external circuitry.
