Abstract

PURPOSE: To secure the easy generation for the large direct current without using any transformer for large current but by using the rectifying bridge which rectifies the input of the direct AC power source, the small current rectification and constant current driving circuit and the commutating capacitor each.
CONSTITUTION: Small current rectification and constant current driving circuit A consists of input AC power terminal 1, rectifying small current thyristors 2aW2f, DC ripple eliminating capacitor 3a, transient controlling reactor 3b, constant current controlling galvanometer 4, constant current setting circuit 5, and phase shifter 6 each. The DC output of thyristors 2aW2f are given to thyristors 7aW7f via the filter comprising 3a and 3b, and thus 3-phase AC generating circuit B is formed. In this case, 8aW8c are commutating capacitors each. Then the rectification is given again at large direct current rectifying circuit C and via thyristors 9aW9f, and then the load is supplied to the direct current.
