摘要： An apparatus for use in the simultaneous deactivation of a set of series-connected switching devices includes gate command control logic to generate a gate command signal for application to a selected switching device of the set of series-connected switching devices. A command compensation circuit processes the gate command signal. The command compensation circuit includes a time differential measurement module that forms a time differential signal indicative of the time from the previous turn-off of the selected switching device and the previous turn-off of the last switching device in the set of series-connected switching devices. A time difference processing module of the command compensation circuit process the time differential signal and creates a delay signal. A delay module of the command compensation circuit delays the gate command signal in response to the delay signal. Each switching device of the set of series-connected switching devices includes a command compensation circuit. Consequently, the generated delay signals cause the series-connected switching devices to turn-off simultaneously.

摘要： The saturation of interphase transformers connected to an inverter is prevented through the use of an inverter switch firing control circuit. The inverter switch firing control circuit includes a control module to execute a standard switch firing scheme to produce a set of inverter pole output signals including a first inverter pole output signal and a second inverter pole output signal, with the first inverter pole output signal having a predetermined phase displacement from the second inverter pole output signal. The circuit also includes a control module to execute a system transient switch firing scheme wherein the inverter reduces the predetermined phase displacement between the first inverter pole output signal and the second inverter pole output signal in the presence of a system transient. This reduction in phase displacement between inverter pole output signals prevents saturation of interphase transformers. Thus, the size, cost, and weight of interphase transformers may be substantially reduced.

摘要： The invention is a locally isolated regulated power supply providing a regulated dc power output from an ac current source having a large dynamic range. The power supply comprises an ac-to-dc converter for providing a rectified dc output from an ac current input. The converter includes a current transformer in combination with a rectifier. The current transformer has a saturable magnetic core for receiving primary and secondary windings. The current transfomer produces a reduced secondary output voltage that is a function of the ac system current characterized by the decreased coupling between the core and secondary winding as the core approaches saturation during substantial increases in the ac system current. One or more secondary windings and associated circuitry can be provided. In addition, an electronically controlled switch or shunt having as inputs a predetermined reference voltage and the dc output voltage of the rectifier or a signal equivalent thereto is connected across the converter. The switch provides for the continual shunting of the converter whenever the dc output voltage is equal to or greater than the predetermined reference voltage. A voltage support capacitor is connected across the output of the converter for maintaining the output voltage proportional to the selected reference voltage. An isolation diode is used to isolate the voltage support capacitor from the converter during those periods of time when the converter is being shunted by the electronically controlled switch. This prevents the discharge of the capacitor.

摘要： A circuit for providing a multiphase digitally synthesized sinusoidal output signal representative of a predetermined symmetrical component set of a multiphase source signal and having a predetermined relationship therewith is taught. The circuit comprises a phase comparator, a phase shifter and a synthesizer. The phase comparator produces an output representative of the phase error in the predetermined phase relationship between the source signal and the output signal. The phase shifter has a variable frequency output for shifting the phase of the synthesized output signal in response to the phase error output signal of the phase comparator. The synthesizer digitally synthesizes at a predetermined amplitude the multiphase sinusoidal output signal. The synthesizer is responsive to the phase shifting output of the phase shifter so as to decrease the phase error between the source signal and output signal. When the phase error has been reduced to substantially a zero value, the output of the synthesizer will lock into a predetermined phase relationship with the source signal. The synthesized output signal can be in phase or in quadrature with the source signal. Either the positive or negative sequence set of the multiphase source signal can be used. In an alternate embodiment, a second synthesizer is provided for producing a second multiphase synthesized output signal that is in quadrature with the first multiphase synthesized output signal that is in phase with the positive sequence set of the multiphase source signal.

摘要： The invention is a method and a circuit for the emergency firing of individual thyristors in a thyristor valve that have a protection circuit for providing an emergency gate control signal for firing the thyristor when the voltage applied thereto equals or exceeds a predetermined initial emergency voltage triggering level. In operation a thyristor is initially fired using the emergency gate control signal produced by the protection circuit when the voltage applied thereto equals or exceeds the emergency voltage triggering level. The emergency voltage triggering level is then reduced. The subsequent firing of the thyristor by the protection circuit occurs when the applied voltage equals or exceeds the reduced emergency voltage triggering level. This allows both economy of operating conditions and protection of the individual thyristor and its associated snubber circuit during prolonged emergency firing conditions.

摘要： Firing signals for the power switches in static power frequency changers are generated by comparing the integral of the output waveform ripple voltage to a repetitively generated stabilizing signal phase locked to, but having a time dependent magnitude independent of, the component waveforms of the output voltage. The stabilizing signal which changes in magnitude in one direction with time is reset to an initial level each time a firing signal is generated.
