摘要： A two-wire load control device (such as, a dimmer switch) for controlling the amount of power delivered from an AC power source to an electrical load (such as, a high-efficiency lighting load) includes a thyristor coupled between the source and the load, a gate coupling circuit coupled between a first main load terminal and the gate of the thyristor, and a control circuit coupled to a control input of the gate coupling circuit. The control circuit generates a drive voltage for causing the gate coupling circuit to conduct a gate current to thus render the thyristor conductive at a firing time during a half cycle of the AC power source, and to allow the gate coupling circuit to conduct the gate current at any time from the firing time through approximately the remainder of the half cycle, where the gate coupling circuit conducts approximately no net average current to render and maintain the thyristor conductive.

摘要： There is described a method for controlling a quenching device for a converter bridge with line regeneration, whereby the converter bridge controlled by a network-timed control circuit by ignition pulses is connected with its three inputs to the phases of a three-phase network and the two outputs of the bridge are connected to a direct-current motor which feeds, when operated as a generator, current back to the three-phase network via the bridge. The quenching device is controlled by a trigger unit which emits trigger pulses depending on the monitoring of electrical and temporary variables. The quenching device comprises, for each bridge half, a quenching condenser that can be charged by a charging circuit quenching voltage. The quenching condensers, in the event of quenching, can be connected to the bridge halves by means of switches that are controlled by the trigger unit.

摘要： A method and an arrangement for controlling phase-specific thyristors of a half-controlled network bridge, the method comprising identifying a thyristor to be controlled on the basis of the magnitude of phase voltage, controlling the thyristor by switching on a voltage in its gate current circuit to achieve a gate current. The controlling of the thyristor comprises the steps of leading the gate current through an inductive component of the gate current circuit to the gate of the thyristor, determining the magnitude of the gate current, alternately switching off the voltage in the gate current circuit, when the gate current is higher than a preset limit, and switching on the voltage in the gate current circuit, when the gate current is lower than a preset limit.

摘要： A gate drive circuit for a silicon controlled rectifier (SCR) connected in an a-c power circuit includes a voltage divider network connected between a d-c voltage source and the SCR for developing a varying voltage on a control node, depending upon whether the anode-to-cathode a-c voltage of the SCR is positive or negative. A first switching transistor, responsive to the control node voltage, controls conduction of a second switching transistor connected between the d-c voltage source and a voltage regulated driver circuit. In this way, a constant drive current is applied to the SCR gate only while the anode-to-cathode voltage of the SCR is positive.
