SiC Modules Enable Power Efficient Designs

Microchip Technology has announced its expanded portfolio of smaller, lighter and more efficient Silicon Carbide (SiC)-power modules. Microchip’s SiC family includes commercially-qualified Schottky Barrier Diode (SBD)-based power modules in 700, 1200 and 1700V variants. The new power module family includes various topologies including Dual Diode, Full Bridge, Phase Leg, Dual Common Cathode and 3-Phase bridge, in addition to offering different current and package options. The addition of SiC SBD modules simplifies designs by integrating multiple SiC diode die with the option to mix and match substrate and baseplate material into a single module—which maximizes switching efficiency, reduces thermal rise and allows for a smaller system footprint.

Demand continues to rapidly grow for SiC-based systems to maximize efficiency and reduce size and weight, allowing engineers to create innovative power solutions, says Microchip. Applications leveraging SiC technology range from electric vehicles and charging stations to smart power grids and industrial and aircraft power systems.

The flexible portfolio of 700, 1200 and 1700V SiC SBD modules utilize Microchip’s newest generation of SiC die, which maximizes system reliability and ruggedness and enables stable and lasting application life. The devices’ high avalanche performance allows system designers to reduce the need for snubber circuits, and the body diode stability allows designs to use the internal body diode without long-term degradation.

The company’s 30kW 3-Phase Vienna Power Factor Correction (PFC), SiC discrete and SP3/SP6LI module drive reference designs/boards provide system developers tools to help reduce development cycle times. The recently added AgileSwitch family of digital programmable gate drivers further supports accelerating the process of moving from the design stage to production.

Microchip’s 700, 1200 and 1700V SiC SBDs power modules are released and available for order. The complete SiC portfolio is supported by a range of SiC SPICE models, SiC driver board reference designs and a PFC Vienna reference design. Microchip SiC products are available in production volumes along with their associated support offerings. A variety of die and package options are available for the SiC MOSFETs and SiC diodes.
