BCM® Bus Converter Module

Family Overview Select a Product

Bus converters

Bus Converters are high-density, high-efficiency, fixed ratio (non-regulating) isolated DC-DC converter modules. BCMs are available in ChiP or a Vicor Integrated Adapter (VIA) package which simplifies cooling as well as providing integrated PMBus control, EMI filtering, and transient protection. The family extends from 800V to 48V inputs with various K factors to suit a wide range of applications and markets. Based on our proprietary Sine-Amplitude Converter topology, high voltage BCM ChiPs are able to reach peak efficiencies of 98% and achieve power densities up to 2,400W/in³. These flexible modules can be easily paralleled into high power arrays and outputs can be put in series to achieve a higher VOUT. BCMs are inherently bidirectional and also allow designers to reduce the amount of bulk capacitance needed at the load by effectively ‘reflecting’ the capacitance across the module based on the specified K factor.  

MIL-COTS versions are also available and operate from MIL-STD-704E/F 270V and deliver an isolated 25.0 – 50.0V, 30.0 – 41.25V, or 38.3 - 55.0V output.
