DC/DC konvertere til gate drive applikationer
Murata annoncerer en serie af 6W DC/DC konvertere, der er optimeret til IGBT, SiC og MOSFET gate drive applikationer (in english).
Murata has announced an extension to their MGJ6 series of isolated 6 Watt dual output DC-DC converters from Murata Power Solutions. Optimized to suit the bipolar voltages required for high-side and low-side IGBT, SiC and MOSFET gate drive applications, the MGJ6 series is available now in SIP, DIP and a low profile surface mount package format.The series comprises combinations of wide input voltages with nominals of 5, 12, or 24 VDC and + 15 / - 5, + 15 / - 10 or + 20 / - 5 VDC outputs. Suitable for low to medium power applications that require a DC link voltage up to 3 kVDC, the asymmetric outputs provide optimum drive levels to maintain a high system efficiency with low EMI levels. Also, with its very low coupling capacitance, typically 15pF EMI coupling through the converter is reduced.
The MGJ6 series has a characterized dV/dt immunity of 80 kV/us minimum at 1.6 kV, this contributing to a high degree of reliability in fast switching drive systems. The series also has characterized partial discharge performance, this being crucial to achieving a long service life in high performance applications.
Certification to safety standard UL60950 for reinforced insulation and the medical 3rd edition safety standard ANSI/AAMI ES60601-1 for 2 MOOPs and 2 MOPPs is currently pending. With a creepage and clearance of 8 mm, the MGJ6 will satisfy safety agency requirements for extra high working voltages.
Murata’s product marketing manager, Ann-Marie Bayliss explains:
- The MGJ6 series provides optimized voltages for power gate drives for the best overall system performance and efficiency. With characterized partial discharge performance, they are now available, in a choice of form factors
Short circuit and overload protection features are standard across the range and a frequency synchronization/enable input pin can simplify EMC filter design.
