DC-DC converters feature high isolation for industrial power installations

Murata has introduced a series of high isolation DC-DC converters. The MGJ6 wide, low-profile series converters feature a 14mm creepage and clearance distance for use in reinforced-rated isolated-gate drive-power applications in higher efficiency 690VAC industrial electrical distribution systems. They provide optimised voltages for best system performance and efficiency. This high isolation series is designed for powering high- and low-side gate-drive circuits for IGBTs and silicon and silicon carbide MOSFETs in bridge circuits used in motor control applications and industrial power installations. Rated at 6W, the dual output converters provide a wide 2:1 input voltage range with nominal values of 5, 12 and 24V, and with output voltages of 15/-10V, 20/-5V and 15/-5V. Suitable for power applications that require a DC link voltage up to 3kVDC, asymmetric outputs provide an optimum drive level to maintain a high system efficiency with low EMI levels. With their frequency synchronisation-capability and very low coupling capacitance, typically 13pF, EMC compliance is easier. As a targeted application solution featuring high isolation construction, high efficiency electronics and planar magnetics, it is claimed that no other manufacturer offers this type of product.
