摘要： A direct current motor which includes a stator for producing a fixed magnetic field and a plurality of armature windings. The motor is caused to rotate by applying current to each winding only while that winding is passing through a zone in a given orientation relative to the stator field. The direction of rotation is changed without changing the direction of the current applied to the windings, by changing the orientation of the zone relative to the stator field, to reverse the direction of the rotational force applied to the armature. Because the current does not reverse through the armature windings, the control circuit can be simple and in a preferred embodiment includes only two gate-turn-off silicon controlled rectifiers, a switch, and a resistor.

摘要： This document discusses, among other things, a system and method for detecting an open secondary condition in a secondary coil of an ignition coil using a control signal received from a control input of a switch configured to control the flow of current to a primary coil of the ignition coil. In an example, the flow of current in the primary coil of the ignition coil can be controlled using an insulated gate bipolar junction transistor (IGBT), and the open secondary condition in the secondary coil of the ignition coil can be detected using a received gate voltage of the IGBT.

摘要： A signal light control system for an automotive vehicle includes silicon-controlled-rectifiers of the gate-turn-off type (GTO), individual ones of which are used to selectively control the conduction of current to signal lamps mounted at the left-front, right-front, left-rear, and right-rear locations on the vehicle. A digital logic network is responsive to the conditions of the turn, hazard, and brake switches of the vehicle, and to the pulse train of a flasher circuit enabled during active conditions of the turn and hazard switches, for selectively applying appropriate control signals to the gate electrodes of the GTOs, to turn on and off the GTOs as required to operate the signal lamps during right and left turn conditions of the turn switch, braking of the vehicle, and the emergency condition of the hazard switch.
