Claim 1
Independent Claim
203 words
A RECTIFYING APPARATUS FOR OBTAINING A REGULABLE DIRECT CURRENT OUTPUT FROM AN ALTERNATING CURRENT COMPRISING AN ALTERNATING CURRENT SOURCE HAVING A PLURALITY OF OUTPUT TERMINALS, RECTIFYING MEANS CONNECTED TO SAID ALTERNATING CURRENT SOURCE FOR RECTIFYING THE OUTPUT OF SAID SOURCE COMPRISING A PLURALITY OF SERIES-CONNECTED CIRCUITS EQUAL IN NUMBER TO THE NUMBER OF OUTPUT TERMINALS OF SAID ALTERNATING-CURRENT SOURCE, EACH OF SAID CIRCUITS COMPRISING A RECTIFIER, A RESISTOR CONNECTED IN PARALLEL WITH SAID RECTIFIER AND A SATURABLE REACTOR HAVING A WINDING, CONNECTIONS CONNECTING SAID WINDING OF EACH SATURABLE REACTOR TO A COMMON POINT, EACH OF SAID RECTIFIERS HAVING A TERMINAL CONNECTED IN THE SAME POLARITY TO A RESPECTIVE OUTPUT TERMINAL OF SAID ALTERNATING CURRENT SOURCE, REGULATING MEANS COMPRISING A REGULATIVE DIRECT CURRENT VOLTAGE SOURCE, A PLURALITY OF RECTIFIYING ELEMENTS CONNECTED TO SAID DIRECT CURRENT VOLTAGE SOURCE, CONNECTIONS CONNECING EACH OF THE RECTIFYING ELEMENTS TO A RESPECTIVE JUNCTION BETWEEN A RECTIFIER AND A RESPECTIVE SATURABLE REACTOR AND CONNECTING SAID RECTIFIERS AND SAID RECTIFYING ELEMENTS IN THE SAME SENSE TO EACH OTHER, THEREBY TO VARY THE VOLTAGE OF THE OUTPUT OF SAID REGULATIVE DIRECT CURRENT SOURCE, AND A SMOOTHING CIRCUIT CONNECTED BETWEEN SAID COMMON POINT OF THE SATURABLE REACTORS AND SAID DIRECT CURRENT VOLTAE SOURCE.
