    摘要: Disclosed herein is a control circuit including an automatically controlled switch coupled in series with a load and an alternating current source, wherein the switch regulates current flow in both directions of flow from the source. A triggering circuit is coupled to a control electrode of the switch for actuating the switch to permit current flow during equal energy portions of both the positive and negative half-waves of the source voltage.

    摘要: A motor control system including a modulator consisting of a saturable reactor, a magnet means and a control means. The magnet means produces a magnetic flux to be supplied to the reactor, which is controlled by the control means, so that the switching means is controlled through the magnet means by the saturable reactor.
