Latest Patents

Kataoka holds a patent for a thyristor starter, which is designed to accelerate a synchronous machine from a stop state to a predetermined rotation speed. This invention operates by sequentially performing two modes: the first mode involves commutation of an inverter by intermittently setting the DC output current of a converter to zero, while the second mode utilizes the induced voltage of the synchronous machine for commutation. The thyristor starter is engineered to raise the induced voltage in proportion to the rotation speed of the synchronous machine by maintaining a constant field current. Additionally, it suppresses the rise of the induced voltage by reducing the field current after the induced voltage reaches a specified threshold.
