Zusammenfassung:	PURPOSE:To perform the stable phase control while synchronizing an inverter with a system by supplying 90 deg. leading synchronizing signal to each phase arm of the inverter through a synchronizing signal transformer and a firing angle regulator from a system phase voltage. CONSTITUTION:A synchronizing signal forming circuit consists of a synchronizing signal transformer 22 and a firing angle regulator 24. System voltages are respectively inputted to the input terminals of 3-phase primary side of the transformer 22, and line voltage is applied to each phase coil. The synchronizing signal voltage obtained from the secondary side of the transformer 22 is inputted to the regulator 22, thereby forming a synchronizing signal to each phase arm of an inverter.
