Converters for high-power transistor driving
27 August 2014
Power Electronics / Power Management
Murata’s MGJ2 series of 2 Watt, dual-output DC-DC converters are suitable for powering high-side and low-side gate drives in bridge circuits using IGBTs and MOSFETs.
They offer basic and supplementary insulation, with an isolation test voltage of 5,2 kV d.c.
Packaged in an industry-standard SIP format, the devices occupy a 1,96 cm squared footprint and achieve a power density of 0,81 Watts per cubic centimetre. The series comprises 12 models offering nominal input voltages of 5, 12, 15 or 24 V d.c. For each input voltage there are three output voltage combinations available:; +15/-5 V d.c., +15/-8,7 V d.c. or +20/-5 V d.c.
The converters have a characterised dv/dt immunity, suiting reliable operation in fast switching applications. Partial discharge performance is also optimised to give a long service life. The MGJ2 series has an extended operating temperature range of up to +100°C that suits industrial grade temperature ratings. Typical applications include high-power AC/DC conversion, motor drives and solar power inverters.
