摘要: A voltage source PWM converter can be used as the input stage to a four-quadrant variable-speed drive give bidirectional power flow, and sinusoidal currents with near unity factor. The paper describes method for line synchronisation control of rectifier which uses indirect supply sensing gives fast update phase angle while rejecting distortion such notches. Indirect allows use standard AC motor without additional hardware or connections. Details at start-up are given experimental results demonstrating robust steady-state dynamic performance presented.
