Power & Motor Control​

BLDC Motor Drivers:

High-voltage motor controller ICs (e.g., TI DRV10987, Infineon TLE9879) supporting 12V–60V systems, enabling Field-Oriented Control (FOC) for brushless DC (BLDC) motors.  These drivers reduce energy loss by 25% vs. brushed motor solutions and deliver precise torque control (±3%)—critical for tasks like drilling through metal or concrete.

Silicon Carbide (SiC) MOSFETs (e.g., Wolfspeed C3M0065090J, ON Semiconductor NVH4L025N120SC1) for high-power tools (1,200W+), with 650V–1200V breakdown voltage and 8mΩ–25mΩ on-resistance.  SiC devices boost efficiency to >97% and handle 3x higher current density than silicon MOSFETs, enabling smaller heat sinks.

Inverter & Power Conversion:

PWM inverter modules (e.g., Mitsubishi Electric PM100CLA120) for AC-powered tools, converting 110V/220V AC to variable-frequency DC to adjust motor speed (500–10,000 RPM) based on load.

DC-DC converters (e.g., MPS MP2307) for battery-powered tools, stepping down 18V–54V battery voltage to 3.3V/5V for control circuits, with 92% efficiency to preserve battery life.
