摘要： A regulator for a closed loop control system receives a sinusoidal reference input signal i* and sums it with a feedback signal i to produce an error signal. A control signal is produced by the regulator by combining signal components which include: (a) a component proportional to the error signal; (b) a componet proportional to the integral of the error signal; and (c) a component related to the frequency of the reference input signal. The latter component insures that an accurate control signal is produced by the regulator over a wide frequency range.

摘要： A current regulator for a variable frequency power supply includes a proportional plus integral circuit that produces a composite control output signal for each phase. To improve the performance of the current regulator at higher frequencies, the composite control output signal for each phase also inlcudes a cross coupled component which is produced by multiplying a d.c. signal proportional to frequency times an integrator output signal from another phase. The composite control signals are applied to a voltage source inverter which produces the output currents to a load.

摘要： Multiple inverter motor drives are interconnected in parallel to provide a common output to a motor. Common control circuitry is coupled to all parallel drives via optical cables and provides signals to power layer circuitry of each inverter for generation, at the power layer, of timing for gate drive signals for the respective inverter power electronic switches. The resulting timing exhibits a high degree of synchronicity such that very little imbalance occurs in the outputs of the paralleled drives, resulting in very low circulating currents.
