| Abstract |
Paper presents theory and test results of sensorless
sinusoidal current active rectifier with controllable waveform of
ac supply current. The rectifier is a source of two dc
symmetrical voltages. The control system operates without ac
voltage sensor and assures stable operation for a case of
symmetrical and asymmetrical dc loads in wide range of the ac
voltage frequency and amplitude. Simulation results and
oscillograms, obtained during laboratory tests, using variable
speed permanent magnet generator, confirm ability of the
simple three bidirectional active switches rectifier, to control of
the current that is not displaced against supplying emf. |
