Isolated gate drive DC-DC converters assists reliable operation in fast switching circuits

The Murata MGJ series DC-DC converters are ideal for powering 'high side', and 'low side' gate drives in bridge circuits using IGBTs and MOSFETs. The converters are now available from TTI Europe. The series is characterised for high dV/dt immunity, which assists reliable and continued operation in fast switching circuits, and partial discharge performance that contributes to a long service life. Also, the converter’s low input-to-output coupling capacitance, typically 5pF, assists in lessening the effects of EMI. Typical applications for the converters are motor drives/motion control, solar inverters, high power AC/DC conversion, welding, medical pump controllers, medical x-ray systems, HVAC inversion systems, electrical powered transportation, and (water) pump and valve control.
