15kW Isolated DC-DC Converter
 |
The 15kW DC-DC Converter is an isolated uni-directional DC to DC converter primarily tailored for operation with a 60-120V rated Fuel Cell power source. This DC-DC Converter produces a galvanically isolated 650V DC bus. Dual Series Boost Stages are used to achieve the desired nominal 650V DC output. |
|
External communication is via an external CAN System Controller. The DC-DC Converter supports paralleling of Modules. This enables higher power conversion to be easily achieved. The output is current regulated to ensure sharing between modules. An inter-Module CAN communications interface cable is required to support this paralleled Mode of operation. |
