摘要： A control for operating an electromagnetic machine in a starting mode of operation wherein the main armature winding of the machine receives electrical power from a controllable power source during the starting mode of operation, comprises a circuit for detecting a magnitude of a parameter of power applied to the main armature winding relative to a stationary frame of reference, a position sensor for detecting rotor position of the electromagnetic machine, a converter responsive to angular position indication for converting the detected parameter magnitude into field and torque producing components relative to a rotating frame of reference, and a circuit responsive to the field and torque producing components for controlling the power source during operation in the starting mode. This control includes an igniter for igniting a prime mover. Further, the control is operable during a first phase prior to ignition of the prime mover for causing the electromagnetic machine to provide motive power to the prime mover so as to accelerate the prime mover at a first predetermined rate, is operable during a second phase subsequent to the first phase so as to accelerate the prime mover at a second predetermined rate, is operable during this second phase for providing fuel to the prime mover to facilitate ignition thereof, and is operable during a third phase subsequent to the ignition of the prime mover so as to accelerate the prime mover at a third predetermined rate to a self-sustaining speed.

摘要： A gate drive circuit for a power transistor provides improved dielectric isolation and protection against inadvertent turn ON of the power transistor. The gate drive circuit includes a first circuit means for providing a bias power signal and a trigger pulse signal to a second circuit means in response to a control signal from an external control circuit connected to said first circuit means. The bias power signal and the trigger pulse signal are coupled from the first circuit means to the second circuit means by magnetic induction through a first and a second coupling transformer, respectively, with the first and second coupling transformers thereby providing separate pathways for coupling of the bias power signal and the trigger pulse signal between the first and second circuit means. The first and second coupling transformers further provide dielectric isolation between the first and second circuit means along each of the separate pathways.

摘要： A current balance arrangement for the power switching devices of a push-pull converter circuit is disclosed. A dynamic dead band circuit is incorporated into a pulse width modulation current balance and output voltage regulation control circuit to prevent current imbalance from causing saturation of the power transformer core for all operating conditions of the converter including input voltage falling below its rated low-line value, sudden load surges, or turning off of the converter power supply. Whenever the dynamic dead band circuit determines that inverter current flow is being terminated by the dead band interval of the converter clock, a control signal is sent to the pulse width modulation circuitry of the converter to effect inverter current termination prior to initiation of the clock dead band interval in subsequent cycles of converter operation. The invention eliminates the need for providing inverter power switching devices having closely matched electrical characteristics.

摘要： An electric power generation and distribution system having a basic variable frequency distribution bus to which wide frequency variation tolerant utilization equipment is coupled and an enhanced frequency distribution bus to which wide frequency variation intolerant utilization equipment is coupled, comprises a variable speed generator driven by an external variable speed prime mover such as an aircraft engine. This generator produces output electric power having a frequency which varies with the speed at which the generator is driven. The system further comprises a converter which is electrically coupled to the generator and produces output electric power having a controlled frequency. A switching network operates to couple the generator to and decouple the converter from this enhanced bus when the frequency of the electric power produced by the generator is within a predetermined acceptable range to allow the generator to supply power thereto. The switching network also operates to decouple the generator from and couple the converter to the enhanced bus when the frequency of the electric power produced by the generator is outside this predetermined acceptable range. The converter then supplies the electric power requirements of the enhanced bus, ensuring that the utilization equipment coupled thereto is not exposed to electric power having a frequency outside an acceptable range. The converter may be operated to match the generator output waveform prior to transfer to allow a no break power transfer between the two sources.

摘要： A gate drive circuit for a power switching device having first and second power terminals and a gate terminal comprises an H-bridge rectifier having first, second, third, and fourth rectifiers, the anodes of the first and second rectifiers being mutually coupled at a midpoint to the cathodes of the third and fourth rectifiers. This midpoint is coupled to the gate terminal of the power switching device. A continuous alternating waveform generator is coupled to output selection control logic which selectively applies the waveform to either a first transformer, whose secondary is coupled to the anodes of the third and fourth rectifiers of the H-bridge for transforming the waveform from a control signal reference system to a power signal reference system, or to a second transformer, whose secondary side is coupled to the cathodes of the first and second rectifiers of the H-bridge for transforming the waveform from the control signal reference system to the power signal reference system. The output selection control logic applies the waveform to the first transformer to drive the power switching device into conduction, and alternatively to the second transformer to drive the power switching device out of conduction.

摘要： A snubber circuit for a power switch includes a capacitor coupled across main current path electrodes of the switch, an inductor having a first end coupled to one of the main current path electrodes of the power switch and a second end and a controllable switch having a first main current path electrode coupled to the second end of the inductor, a second main current path electrode coupled to the other main current path electrode of the power switch and a control electrode. A control circuit is coupled to the power switch and the controllable switch and turns on the controllable switch when a gating signal is commanding turn-on of the power switch and the voltage across the main current path electrodes of the power switch is above a certain level so that the capacitor is discharged through the inductor at such time. The control circuit subsequently turns off the controllable switch and turns on the power switch while the gating signal is commanding turn-on of the latter switch when the voltage across the main current path electrodes thereof falls below the certain level.
