Abstract

See full text

A method and system of igniting one or more filaments for silicon production includes applying an output voltage to the one or more filaments using a transformer connected with the one or more filaments. In addition, the method includes supplying, in combination with the application of the output voltage, a current to a primary winding of the transformer via a choke to limit the current to a first predetermined current threshold range. The combination of the supplied current and applied output voltage allows a predetermined output range to be generated from a power supply device initially required to ignite the one or more filaments.
