New High Isolation DC-DC Converter for High-Power Converter Applications

Power electronics specialist, Amantys Power Electronics Limited, has today announced the launch of a high isolation DC-DC converter to power high voltage gate drives for 4500V and 6500V IGBT modules. The DC-DC converter is designed to comply with international standards including EN 50155 for railway applications and IEC 61800-5-1 for variable speed motor drives. 

The DC-DC converter can accept a 15V or 24V input voltage and has an output power of up to 15W making it suitable for driving several gate drives in parallel. It features low quiescent current of 50mA and a maximum current output of 1100mA. The DC-DC converter provides a minimum of 12kVrms working voltage isolation, making it suitable for two level and three level converter topologies.

The robust design can operate from -40ºC to +85ºC and has protection features for: input reverse polarity; input overvoltage; output short circuit; and output overload. The protection features are complemented by status LEDs that indicate DC-DC operation and fault conditions.

The isolated DC-DC converter will be used in applications such as railway traction, HVDC infrastructure and medium voltage motor drives. The DC-DC converter is available for sample orders in Q4 2016.
