Patent ID: 8829711

Claim:
A modular power supply arrangement in a reactor producing polysilicon, the power supply comprising: a power mains; a central control module haying an input connected to the power mains supplying the central control module with electrical energy, the central control module including, at least one controller; at least one basic supply module haying at least one input supplying the basic supply module with electric energy; and the at least one basic supply module having at least one output connecting to a group of loads to receive electric energy from the power mains via the basic supply module; the basic supply module being controlled and/or regulated by the controller of the central control module; the basic supply module further including controllable switches, connected at least indirectly to the input and to the output of the basic supply module, the controllable switches increase or decrease the energy supplied by the power mains to the loads via the output, wherein each of the switches is switchable by the central control module between two states to form an open circuit and a closed circuit; a communication bus connected to the central control module and the basic supply module via an interface; and a voltage supply module supplying higher voltages than an output voltage of the power mains, the voltage supply module comprises at least one input connected to the power mains supplying electric energy or a transformer for supplying electric energy and outputs connected to one corresponding load from the group of loads; an interface connecting the voltage supply module to the communication bus; the voltage supply module further includes a plurality of converters for generating from the power mains at the input, of the voltage supply module a voltage of higher frequency; the voltage of higher frequency is upconverted by a plurality of transformers to produce a higher voltage than that of the power mains: wherein the plural transformers includes a first transformer, a second transformer, a third transformer, and a fourth transformer; each of the transformers having a plurality of outputs; the first and second transformers together represent a first pair of transformers, while the third and fourth transformers together represent a second pair of transformers; outputs of the plural transformers provide the outputs of the voltage supply module; linked voltages across the outputs of the voltage supply module are equal to 0 V at least during a time when loads connected to the outputs of the voltage supply module are supplied with electric power.
