The unregulated fixed-ratio 2.5kW isolated bi-directional 800V to-from 48V dc-dc converter is a member of the BCM6135 family, with a power density of 158kW/litre according to the company.
“The bidirectional rapid current transient response rate of 8MA/s allows the BCM6135 to replace a 25lb 48V battery, serving as a virtual 48V battery,” said Vicor.
Pre-charging high-voltage inverters from a low-voltage battery is another potential application.
DCM3735 is the 2kW 48V (35 to 58V) input non-isolated converter that produces a regulated 12V output, trimmable across 8 to 16V, measuring 36.6 x 35.4 x 7.4mm.
Claimed power density is 300kW/litre, and the company said: “DCM3735 can be mounted remotely to create a local 12V supply in a vehicle zone, for example on the right-hand side.
PRM3735 is a non-isolated 2.5kW dc-dc that converts an input between 31 and 58V to a nominally 48V regulated output, adjustable between 36 and 54V.
It measures 36.6 x 35.4 x 7.4mm.
Automotive grade?
“The modules cannot be classified into any of the AEC categories so we cannot qualify the final part – BCM6135 for example – to an AEC level,” the company told Electronics weekly. “However, the parts are tested to numerous automotive ISO and SAE standards as part of the PPAP process.”
