Latest Patents

Takahiro Ota holds a patent for a thyristor starter. This invention involves an inverter that converts DC power from a converter through a DC reactor into AC power with a variable frequency. The AC power is then supplied to a synchronous machine. A controller manages the inverter based on a phase control angle, while a voltage regulator ensures the induced voltage of the synchronous machine is maintained by supplying field current. Notably, when the rotation speed of the synchronous machine exceeds a reference speed during acceleration, the voltage regulator adjusts the field current to increase the induced voltage in line with the rotation speed. The controller also modifies the rate of increase in the phase control angle relative to the rotation speed, optimizing performance.
