摘要： An excitation system for a brushless synchronous alternator includes an exciter having a stator which includes first and second sets of field coils respectively coupled to a source of DC power and in series with polyphase AC output current developed by the main generator. A base level of exciter field current is provided by the DC current delivered to the first set of field coils while a second variable amount of field current is provided by the AC output current delivered to the second set of field coils. The exciter also includes a rotor structure having first and second sets of armature windings which develop first and second exciter currents in response to movement of the rotor structure within the magnetic fields set up by the first and second sets of exciter field coils. The first and second exciter currents are added, rectified and delivered to a set of main generator field windings. By dividing the responsibility for providing exciter field current in this fashion, transient response is improved and overall length and weight of the generator package are decreased.

摘要： A generator system which is self-excited even during a fault condition includes a main generator having armature windings and a main field winding which is excited by a rotary transformer. The rotary transformer includes a stationary primary winding and a rotating secondary winding, with the primary winding receiving a controlled portion of the main generator armature output. The current through the primary winding of the transformer is controlled by silicon controlled rectifiers which are gated by a voltage regulator circuit. The voltage regulator circuit in turn receives signals from the voltage delivered to the load, the highest phase current delivered to the load and the voltage at the main generator armature output. The voltage regulator controls the current through the primary winding of the transformer in accordance with the voltage delivered to the load if that voltage is greater than a predetermined value. If the voltage delivered to the load is less than the predetermined value, such as when a fault condition arises, the current through the primary winding of the transformer is controlled in accordance with the voltage at the main generator armature output. A current limiter is also provided to limit the output current from the main generator armature during a fault condition to maintain the voltage of the generator armature at acceptable levels for self-excitation.

摘要： An improved rotor assembly for a generator used in a multi-channel parallel electrical generating system. A plurality of laminated sections, each having N outwardly extending poles, are stacked to form a rotor. Field windings are wound around the N poles and damper turns are wound around adjacent pole pairs to reduce the mutual flux coupling between the rotor and the stator, thereby reducing the fundamental component of torque between the rotor and the stator.

摘要： An electromagnetic energy storage and supply system for supplementing a main power supply to provide D.C. current to a pulsed load by providing that portion of the load current which is above the average load current commanded. The load current is sensed and compared to an average current command to provide a difference signal which is proportional to a desired supplemental current to be provided to the load. An inverter, coupled between the main power supply and a motor, is controlled during the off period of the pulsed load and in response to the difference signal to provide an A.C. signal to the motor which in turn drives an inertia device coupled thereto for storing energy. During the on period of the pulsed load the inertia device decelerates, discharging energy through the motor and inverter to provide the supplemental D.C. current to the load.

摘要： A bidirectional inverter circuit for evenly distributing energy among two capacitors in a DC power supply of a pulse width modulated inverter which provides an AC output to a load. The bidirectional inverter circuit is responsive to a greater charge on one of the power supply capacitors than on the other to divert regenerative current flowing to the power supply from the load away from the one capacitor and to transfer charge to the other capacitor.

摘要： An in-line voltage balancing circuit sums a trim voltage with each phase voltage of a polyphase generating system to assure that the voltage between each phase and neutral is equal to the average voltage of all the phases. An individual error signal representative of the difference between each phase voltage and the average voltage is provided to individual phase modulator circuits. The phase modulator circuits develop pulse width modulated signals wherein the pulse width is proportional to the amplitude of the error signal. The outputs of the phase modulator circuits are connected to switching amplifiers which provide trim voltages proportional to the phase modulated signals. Summing transformers are employed to sum the individual trim voltage with appropriate phase voltage so that the voltage for each phase equals the average voltage.

摘要： A DC to AC inverter in which a composite waveform synthesizing a sinusoidal waveform and having three incremental steps for each quarter cycle is formed by summing an alternating stepped waveform having three steps for half cycle, with a square wave in phase therewith and having a frequency three times greater than the alternating stepped waveform. In a three-phase embodiment of the inverter, each of three stages has a coil that is appropriately switched to opposite polarity terminals of a DC voltage source to form beginning and end segments of the alternating waveform, and a single square wave for all three phases is developed by three series-connected windings respectively inductively coupled with the three coils. The single square wave is added to all three alternating stepped waveforms to form the three composite output waveforms of the inverter.
