Abstract
PURPOSE: To prevent uneven magnetization of the transformer core by overlapping a DC voltage over the AC voltage applied at the primary of transformer or supplying a DC current through additional winding for the DC current at the secondary of transformer.
CONSTITUTION: Assuming the conducting phase of each thyristor in semi-bridge inverter comprising the thyristors 25, 26 is 180°, the voltage applied at the primary of transformer 13 becomes rectangular. Assuming the DC voltage 23 is E1 and the DC voltage 24 is E2 the DC voltage applied at the primary of transformer 13 is shown by (E1-E2)/2, thereby when determining said DC voltage (E1-E2)/2 such that the primary equivalent in the current detector 21 and the detected level in the current detector 18 go to zero, the uneven magnetization of transformer 13 can be prevented by controlling the voltage E2 of DC power source 24.
