The Vicor family of High Voltage BCMs are high efficiency and high-power density bus converters which provide an isolated intermediate bus voltage to power non-isolated point-of-load converters.
Using the Vicor unique Sine Amplitude Converter™ topology with fixed high switching frequency and zero voltage and zero current soft switching, the MIL-COTS BCMs offer direct ratio-metric conversion from a 270V NOM input to a range of DC outputs. With millions of hours of operation in the field, the BCM has a demonstrated ability to exceed the stringent reliability requirements needed in defense-based applications. High Voltage MIL-COTS BCM products provide power system engineers superior performance with benchmark efficiency and power density and eliminates constraints of size and height in a design with smaller, lighter and low profile packages.
These products are available in multiple package options including surface-mount and through-hole VI Chips, through-hole ChiPs and chassis or PCB mount VIAs that provides design flexibility and enables multiplicity of thermal design strategies.
Applications
For use in a broad range of defense-based IBA power systems that can run from 270V DC MIL input voltage. Applications include airborne power, high density defense/aerospace power systems and defense/aerospace communications systems.
