Latest Patents

Matsuda's latest patents focus on advanced motor control apparatuses and methods. One of his notable inventions includes a motor control apparatus that features a voltage regulator. This regulator executes a voltage increase mode to gradually increase the voltage applied to an induction motor from a lower limit of a first range over time. Additionally, a frequency regulator is designed to execute a frequency decrease mode, which decreases the frequency of the voltage from an upper limit of a second range over time. The frequency regulator also limits the decrease of frequency when a bus voltage exceeds a first threshold during the frequency decrease mode. This bus supplies DC power to an inverter that drives the motor. The mode changer in the apparatus alternates between the voltage increase mode and the frequency decrease mode to control the motor's transition from a free-running state to a state where the voltage and frequency meet specific relationships. A determinator is included to assess whether these conditions are satisfied.
