摘要： A control apparatus and method are provided for a load energized by an inverter coupled with a DC power source. The lag current angle between the current and the load voltage is utilized to determine when the output current is positive and when the output current is negative. The conduction times of the respective upper and lower gate turn off thyristors of each pole of the inverter are controlled in relation to the established current angle, with a provided modification of those conduction times being phased out in response to the desired output voltage for said load.

摘要： An electric-motor-driven circulating pump for heating systems reduces power consumption of the motor, whereby the reduction ensues by means of periodic interruption of a line feed by means of electronic switch means so that switch-on and pause intervals follow one another. The switch means interrupt or close current flow at a zero-axis crossing of the voltage of the line feed.

摘要： A variable motor speed control arrangement of the tachogenerator feedback loop type comprises a triac (5) connected in series with the motor (M). The triac is fired in each half cycle of the AC mains supply. The firing angle of the triac is varied to provide the required control. The arrangement employs a single cycling counter (CT) to time the interval between two output pulses of the tachogenerator (T) in order to determine the current motor speed and also to provide a count-down from the beginning of each half cycle to the required firing instant. The control processes are carried out in periods beginning at each counter overflow instant. This breaking up of the processing, together with the use of the single counter allows a microcomputer (1), which is running other programs to provide the speed control in addition.

摘要： A motor control circuit is provided for controlling the acceleration, speed, deceleration, stopping and direction of rotation of a drive motor which drives a mechanized filing cabinet. The control circuit is packaged so that it may be connected through electrical connectors to the drive motor, safety interlocks, and automatic and manual controls available on existing mechanized filing cabinets. It may be used with existing mechanized filing cabinets having manual, automatic, or both manual and automatic controls for driving the carrier bins in a cabinet in the shortest direction around an orbital path to a position opposite an access door. Under automatic control, the drive motor is accelerated to a fast speed and maintains this speed until the desired carrier bin approaches the access door. The drive motor is then driven at a slower rate as it comes into the desired position. A two-step braking circuit stops the motor in such a manner that the contents of the carrier bins are not thrown about. A feedback signal from the motor is used to regulate the speed of the motor and prevent excessive speed when an unbalanced load is carried in the carrier bins. Circuits are provided for preventing the inadvertent application of a reverse voltage to the motor while it is rotating.
