Compact, lightweight dc-dc converter meets railway standards

Premium’s CBS-10K dc-dc converter series is available from Relec Electronics. The compact converters are designed to provide peak power hybrid diesel-electric trains when catenary power is not available.

The CBS-10K dc-dc converters feature galvanic isolation between input and output, operating at fixed switching frequency. The single output dc-dc converter has multiple I/O combinations to meet industrial and rail applications which require high power conversion in a compact design. The dc-dc converter provides up to 6kW average power and peak power up to 10kW for 40s to protect against overload and short circuits.

The modules can provide 500Vdc output (up to 700Vdc on request). Premium developed the dc-dc converter series with SiC (silicon carbide) technology to increase power density.

Input options are 24Vdc, 48Vdc, 72Vdc and 110Vdc. All models can be operated in parallel. The high I/O isolation is 5,000Vrms and the design includes an ORing diode at the output to decouple it from lines up to 2kV.

Other features include opto-coupled remote off and an isolated relay contact alarm. Efficiency is up to 95% and MTBF is 200,000 hours (according to IEC61709, SN29500 at 40°C).

The dc-dc converters in the CBS-10K series have remote control functionality via RS232, with optional CAN bus.

The CBS-10K series is designed to meet EN50155 for railway applications. The dc-dc converters are designed to rolling stock standards. At start-up, it supplies the rectifier in order for it to operate as an inverter. It allows hybrid diesel-electric trains to operate at low speeds when overhead electrical wires are not available.

The series is also approved to EN45545-2 (fire and smoke). Use cables of adequate cross-section to connect inputs and outputs.

The railway module is covered by the manufacturer’s five year warranty and the industrial module has a three year warranty. Both are available from Relec Electronics.
