Today, traditional inverters and converters based on silicon IGBTs make up most of the market (>70%), primarily due to electrical motor drive applications in factory production lines and to the first generation of wind and solar inverters. The power converter market is growing with a CAGR of more than 6.5% and is expected to reach a value of 80 billion dollars by the year 2021. Power converter market forecast for the year 2021. Together with the ADSP-CM419F high end, mixed-signal control processor, they both can manage the high speed, complex multilevel control loops of the high density, SiC-/GaN-based, next-generation power converters.įigure 1.
H BRIDGE MOSFET DRIVER DRIVER
ADI’s ADuM4135 isolated gate driver has all the required technical features integrated in a 16-lead, wide-body SOIC package. For SiC and GaN MOSFETs, high CMTI >100 kV/μs, wide gate voltage swing, fast rise and fall times, and a very low propagation delay are needed.
H BRIDGE MOSFET DRIVER DRIVERS
Requirements for isolated gate drivers are changing from past silicon IGBT drivers.
To take all the advantages of the new power switch technologies, a complete ecosystem of ICs must be implemented in converter design, starting from the closest chip to the power switch, the gate driver. New high efficiency, ultrafast power converters based on wideband gap (WBG) semiconductors like silicon carbide (SiC) and gallium nitrite (GaN) MOSFETs are starting to expand in various innovative markets and applications-namely solar PV inverters, energy storage, and vehicle electrification (for example, chargers and traction motor inverters). This also means having higher working voltage to manage higher power without increasing weight and dimension, like in solar string inverters and electric vehicle traction motors.
New challenges are arising, such as the need to make smaller and more efficient power converters that can serve smaller servo drives or be integrated into distributed energy storage units. Introduction The power converter market is and will be evolving fast, moving from simple performance/cost designs to broader and more sustainable innovation.
