Abstract
PURPOSE: To obtain the AC power control unit which can reduce the leakage magnetic flux, by leading the both ends of the secondary winding of the transformer at the leading terminals with the leads and outputting them via the thyristor in anti- parallel connection.
CONSTITUTION: The output end of the secondary winding of the three phase transformer 1 consisting of the primary winding 2 and the secondary windings 3aW3c is connected with the lead terminals 7aW9b through the leads 4aW6b, the terminals 7aW9a are connected to the thyristor units 10W12 to flow the current in-phase but reverse direction between the circuit of the thyristor unit 10 and the leads 4b to conductor 15a, and similarly in-phase but reverse current flows to the thyristor unit 11 and conductor 15b, thyristor unit 12 and conductor 15c, the synthesized magnetic field produced is very small and the induction current due to leakage magnetic flux is very small, allowing to avoid overheating.
