Murata has introduced a series of high-isolation IGBT DC modules developed by Murata Power Solutions. The MGJ series of wide, low profile modules with 14 mm creepage and clearance distances are ideal for enhanced isolation barrier drive power applications in high isolation industrial power distribution systems. They provide optimized voltages for optimum system performance and efficiency. MGJ's high-isolation IGBT DC module offers a wide 2:1 input voltage range, rated at 5, 12 and 24V at a rated power of 6W and an output voltage of +15V/-10V. Configurable dual output voltages of +20V/-5V and +15V/-5V, the outputs are used in a variety of applications and can be connected in parallel or in series. The MGJ includes new through-hole SIP and DIP components, as well as surface mount options.

The MGJ half-bridge, full-bridge and three-phase modules are primarily designed to drive the high-side and low-side gate drive circuits of IGBTs, as well as silicon and silicon carbide MOSFETs in bridge circuits for motor control applications and industrial power supply installations. The choice of asymmetrical output voltage allows for optimal drive levels for optimum system efficiency and EMI. The MGJ Series meets the high isolation and dv/dt requirements common in bridge circuits used in motor drives and inverters.

The MGJ components have two, three, and four independent outputs, which can be easily configured externally with a simple circuit to provide positive and negative voltages for gate drive power. Only one component can be used to power all gate drivers in a bridge application, and can save up to 33% to 50% space. For example, in a three-phase bridge, the four-output MGJ63P provides isolated power to three high-side switching drivers, as well as a shared power rail to three low-side switch drivers, and can even replace up to six discrete DC-DC converters. Device.

The MGJ Series is suitable for power applications requiring DC link voltages up to 3 kVDC, and the asymmetric output provides optimum drive levels to maintain high system efficiency at low EMI levels. With its frequency synchronization and very low coupling capacitance (typically 13 pF), it is easier to meet EMC specifications.

The compact design of the MGJ converter reduces board space and development time, while its 80kV/microsecond dv/dt immunity provides users with confidence in the long-term operation of the product. The built-in planar magnetic components can also be used. Improve product reliability and repeatability of performance. MGJ is ideal for gate drive circuits that supply power to IGBTs in applications where high isolation and high efficiency are important. Typical applications include motor drive/motion control, solar inverters, UPS, substation, alternative energy (wind generators), high power. AC-DC converters, traction motors, electric/hybrid (EV/HEV) and welding applications can also be used in medical applications such as X-ray machines, computed tomography (CT) and magnetic resonance imaging (MRI), ultrasound machines, Defibrillators are also used in railway and industrial applications.

The MGJ series of converters have an operating temperature range of -40 to 105 °C and a derating rate of over 90 °C. Standard features of the patented converter include enable pins, short circuit and overload protection, and frequency synchronization pins that simplify EMC filter design.

The MGJ series is awaiting IEC 61800-5-1 certification based on the maximum workload between primary and secondary voltages, and it is also applying UL UL reinforced insulation certification for UL 60950 to enhance the operating voltage of 690 Vrms. Reduce the overall cost of system certification. In addition, 2xMOPP certifications for ANSI/AAMI ES60601-1, 2xMOOP, and different system voltage levels are under review, which will simplify the system's medical application approval process.

MGJ is a targeted application solution with high isolation structure, high efficiency electronic components and planar magnetic components. Currently, other manufacturers have not provided such products, MGJ will be the best choice for your development needs high isolation products.
