In railway-applications, a DC/DC-converter has to power frequently various load-branches. These load branches are often individually protected with circuit breakers to isolate them selectively in case of a fault. In case of such a fault (short-circuit), the DC/DC-converter must be able to source enough current to trip the circuit breaker reasonably. For this purpose, the overload and short-circuit behaviour of the DC/DC-converter is vitally important.
The newest intreXis 500 W DC/DC-converters have a new power-boost capability which can:
All DC/DC-converters of our intreXis Boardnet Converter Platform are continuously overload and short-circuit proof. No overheating or damage will occur to our DC/DC-converters during any overload or short-circuit event.
Test and measurements were carried out with the 500 W DC/DC-converter, 24 V output voltage (IC303_1), to confirm the peak-power capability and tripping of various circuit-breakers.
