Title: Daiki Mizuguchi and His Motor-Control Patents.

Introduction

Daiki Mizuguchi is an inventor based in Kariya, Japan, whose patent work focuses on electric power conversion and motor-inverter control. He is associated with Kabushiki Kaisha Toyota Jidoshokki and has 2 patents.

Latest Patents

Mizuguchi’s listed patents address control techniques for power electronics and three-phase motors.

“Power conversion system” describes a method for discharging a smoothing capacitor located between a battery and an inverter. The control circuit alternates between all-phase upper-on and all-phase lower-on control. For a prescribed period, it sets modules carrying negative current to the lower-on state and modules carrying positive current to the upper-on state.

“Control method and control device of motor inverter” concerns two-phase modulation for a three-phase motor. The control device identifies a stationary phase for each area of the rotor’s electrical rotation, using the motor’s d-axis and q-axis current command values. It then switches the elements in the other phases to drive the motor.
