Rectified current supply for asynchronous machine - uses feedback control signal obtained from machine voltage vector

摘要

The rectified supply circuit, allows a number of asynchronous rotary electrical machines to be supplied with a variable voltage and includes an output capacitor for compensation of the imaginary load. The circuit comprises a controlled current rectifier and control means for the latter supplied with a signal obtained from the machine voltage. This signal is obtained by weighting a linear combination of the real and imaginary components of the machine voltage vector.
