Title: Drive device of motor group
Inventor: JOFU TOSHIAKI
IPC: H02P5/74
Filed: 1984-09-04
Abstract: PURPOSE:To reduce the output capacity of an inverter by fixing one switching element which forms an inverter to OFF when the output current level becomes the prescribed value or higher, and controlling ON or OFF the other switching element as usual. CONSTITUTION:If the output current level of an inverter 10 exceeds a reference level, a switching element at the positive arm side of the inverter 10 is fixed to OFF, and a current supply from the inverter 10 is stopped. However, since the switching element of the negative arm side is controlled ON and OFF as usual at this time, the reactive current between the inverter 10 and a motor M continues to flow to a defective motor side while gradually reducing. Accordingly, sufficiently large current can be continuously flowed to the defective motor side within the capacity range of the inverter until protection fuses EF1-EFn melt.
