Title: Axial generating set for constant frequency/voltage
Inventor: ITANO SUMINORI
IPC: G05F1/70
Filed: 1978-12-04
Abstract: PURPOSE: To ensure the feed within the ship although the output of the axial generator may lower to some extent by providing the voltage control circuit to the inverter of the axial generator of the ship and thus detecting for control the degree of lowering for the output voltage of the generator compared with the rated voltage.  
     CONSTITUTION: When propeller engine 1 in the ship is operated under the normal operation range, automatic voltage controller 5 is saturated. And the voltage lower than the rated voltage is delivered from axial generator 4. Thus voltage detector circuit 12 applies the voltage lower the rated voltage delivered to the voltage limit circuit in inverter control circuit 11. Circuit 11 gives the control so that the control advance angle of inverter 9 may be increased in accordance with the output lowering voltage of circuit 12. As a result, the control advance angle of inverter 9 increases although the output of generator 4 lowers down, and thus the DC voltage necessary for the inverter becomes low. Accordingly, a sufficient amount of current flows to the inverter from converter 7 to continue the operation, thus increasing the range of feed within the ship.
