Electric boosting power supply system for flexible glass kiln

The invention provides an electric boosting power supply system for a flexible glass kiln, which comprises single single-phase output adjustable power supplies and a synchronous signal control box, the number of the single single-phase output adjustable power supplies corresponds to the number of electrodes in the electric boosting kiln, the synchronous signal control box is connected with the adjustable power supplies through optical fibers, the single-phase output adjustable power supplies are phase-adjustable power supplies with IGBTs (insulated gate bipolar transistors) as power control modules, and the synchronous signal control box is connected with the synchronous signal control box through optical fibers. The synchronous signal control box is used for providing multiple paths of synchronous signals for the single-phase output adjustable power supply and controlling the output phase of the single-phase output adjustable power supply by adjusting the mutual time difference among the multiple paths of sy
