Bus converter

Powerbox has released Vicor’s VI Brick BCM bus converter, a member of the VI Brick family that provides a modular power platform for power solutions.

The modules use sine amplitude converter technology, thermally adept packaging and manufacturing processes to provide high-power density and efficiency, good transient response and improved thermal management.

The modules can be used to provide an isolated intermediate bus to power multiple non-isolated POL converters or as an independent power source.

The device has efficiency up to 96% operating from primary bus voltages of 48 and 350/380 to deliver isolated outputs with a range of voltages from 1.5 to 48 DC depending on the model.

Due to the fast response time and low noise, the need for capacitors at the load is reduced — or eliminated.

This is complemented by the capacitive multiplication effect of the BCM where the required input capacitance of the niPOL can be reduced, by a factor of the square of the BCM transformation ratio, by placing the capacitance at the input of the BCM.

The converter may also be used in high-power, high-efficiency data centre applications to power individual cards or blades directly from the HV distribution bus.
