PURPOSE:To reduce a loss by limiting the utility of an absorber circuit to a thyristor which forms a rectangular wave output bridge inverter having an induction load. CONSTITUTION:Two thyristors 23, 24 are connected in series with both ends of two DC power sources 21, 22 connected in series, diodes 25, 26 for feeding back energy are connected in anti-parallel with the thyristors 23, 24, and an inductive load 27 is connected between the connecting point of the power sources 21, 22 and the connecting point of the thyristors 23, 24. Capacitors 28, 29 are connected in parallel with the thyristors 23, 24, and all operated as absorber circuits. After the discharges of the capacitors 23, 24 are completed, the thyristors 23, 24 are fired. |
