Latest Patents

One of his latest patents is an "Excitation system for synchronous machine." This invention simplifies the adjustment work of current distribution to thyristors. The synchronous machine regulator features a circuit board that mounts a gate drive circuit, which supplies a gate pulse to each thyristor bridge. These bridges constitute a plurality of thyristor rectifiers connected in parallel, supplying excitation current to a field winding of a synchronous machine. The phase control means in this system controls the phase angle of each gate pulse supplied to each thyristor, thereby managing the current distribution effectively.

Another significant patent is the "Excitation control apparatus for a generator." This field control apparatus is designed for a generator with a field winding. It includes a terminal voltage control unit that regulates the field current based on the difference between the terminal voltage signal and a reference voltage signal. This control unit incorporates various functions, such as line drop compensation, under-excitation limitation, and power factor regulation. The apparatus also features a detector that identifies active and reactive power components at the generator's output terminal, enhancing the overall efficiency of the excitation process.
