Abstract
A polyphase rectifier system which provides two output current-voltage ranges upon the system direct current output circuitry. Each phase of a polyphase potential source is rectified by a respective rectifier circuit having the alternating current input circuit thereof electrically connected to the output electrical coil of the corresponding phase of the polyphase potential source and the direct current output circuit thereof connected in parallel with the direct current output circuit of all of the other rectifier circuits. An electrical switching means operable to the electrical circuit open and closed conditions is provided for electrically interconnecting one terminal end of all of the output electrical coils of the polyphase potential source when operated to the electrical circuit closed condition.
