Hello, I’m Hanlin.
Exploring the power behind computation.
I study point-of-load (POL) power supplies for AI data centers at Tohoku University, with a focus on low-voltage, high-current DC–DC conversion and multiphase buck circuits. From circuit simulation to industry experience, I aim to turn technical understanding into practical problem-solving.

02 / Research
Supporting AI, one power stage at a time.
My focus is the final voltage-conversion stage close to the chip: understanding efficiency, power density, and dynamic response at low output voltages and high currents.
Modeling & transient response
Using MATLAB / Simulink and LTspice to model circuits and investigate PWM control, output ripple, and responses to changing loads.
Devices in a system context
Working with development boards, schematics, and published technical material to connect power devices and controllers with AI data-center power architectures.
