Title: Inverter output decreasing system
Inventor: WATANABE TOSHINORI
IPC: H02M7/515
Filed: 1979-11-07
Abstract: PURPOSE:To prevent the occurrence of the commutation failure of the inverter by advancing the firing signal of a delay phase thyristor when the output current of the inverter exceeds a predetermined value and interrupting the delay phase firing controlled thyristor conducting. CONSTITUTION:The output from the inverter 19 is supplied through a transformer 20 to a load circuit. The current flowing through the load circuit is detected by a current transformer 113, and when this value exceeds the overcurrent detecting level, the detecting circuit 115 produces an output to a gate circuit 116, thereby switching the gate signal of the gate circuit 116. The gate circuit 116 advances the firing signal of the delay phase thyristor and interrupts the delay phase firing controlled thyristor conducting by gate signals G1-G4, which are inputted to the gates of the respective thyristors 1-4. Accordingly, the output current of the inverter 19 is suppressed.
