TOP-electronics is pleased to announce the release of Apex Microtechnology 's MSA303 - a compact, 3-phase Silicon Carbide (SiC) Integrated Power Module designed for high-power motor drive applications.
Three fully independent half-bridges
By integrating three half-bridges, gate drive circuitry, and protection features into a single module, the MSA303 supports system design where size, weight, and power (SWaP) are critical. Its compact architecture enables high-power delivery within a small footprint, optimizing space in demanding application environments.
The MSA303 is a fully integrated three-phase driver designed primarily to drive Brush-Less DC (BLDC), Permanent Magnet Synchronous (PMSM) motors or, DC/AC converters. The module uses Silicon Carbide MOSFET technology to improve efficiency over other devices in its class. Three fully independent half-bridges provide 40 A of continuous current. MSA303 is built on a thermally conductive, but electrically isolated sub-strate to provide the most versatility and ease in heatsinking.
Protection features include under-voltage lockout (UVLO) function and active Miller clamping to improve reliability. Also included in the module are Silicon Carbide Schottky Barrier free-wheeling diodes in parallel to the body diode of each MOSFET. No external output protection diodes are required.
Integrated gate driver
MSA303's integrated gate drivers provide isolation between the inputs and high-voltage outputs. By integrating the gate drive with the output MOSFETs, parasitics that impact the switching behavior are kept at a minimum, improving the switching characteristics while reducing potential oscillations.
