The Vicor 48V power module ecosystem: solutions for the entire power delivery network
Vicor high-density modular power conversion is essential in space-constrained designs that require flexibility and scalability. Power modules’ low noise simplifies filter design, and their thermally-adept packaging simplifies thermal management to significantly reduce power losses. The broad Vicor ecosystem of advanced power modules, architecture and topologies simplify the transition to 48V by allowing for quick prototyping and implementation of a complete 48V power delivery network.
The Vicor ecosystem allows you to:
- Reduce the size and weight of power systems
- Enable the efficiency gains of a 48V bus
- Quickly implement tested and reliable solutions
High performance power modules optimized for 48V power delivery networks
Modules that convert high voltage to 48V efficiently
The initial element for power designs is the conversion of rectified AC or high-voltage DC inputs to 48V. Isolated, high-efficiency converters are used to step down from voltages such as 800V or 400V. Industry-leading power density and innovative architectures of Vicor power modules equip power designers with either isolated or non-isolated solutions that reduce the size and weight of power systems and provide the most efficient solution establishing a 48V bus.
Modules that power the point of load from a 48V bus
48V-to-PoL (point-of-load) converters deliver power to processors, sensors, motors and other points-of-load. Vicor DC-DC modules — buck and buck-boost converters, voltage regulators and fixed-ratio DC-DC converters — provide high power at low voltages, offer fast transient response and precise voltage regulation in compact form factors with superior size and weight performance.
Modules that enable 12V/48V compatibility
48V and 12V compatibility eases the transition to 48V and allows legacy 12V loads to coexist with new 48V architectures. Vicor bidirectional and conventional converters support gradual upgrades that enable hybrid mixed-voltage environments and compatibility with off-the-shelf components. This alleviates the burden of completely redesigning systems that for decades have been optimized around 12V architectures.
