摘要: The invention discloses a permanent magnet starting power generation system with an open-circuit fault-tolerant capability and control method thereof. A starter generator is high-impedance synchronous motor, bidirectional bridge converter has redundant arm to continuously detect the motor winding current when starts outputs stable direct voltage, so as realize vector fault detection. When open circuit of switching tube detected, driving signal where faultyswitch located blocked, corresponding thyristor turned on, replaces faulty work; connected neutral point midpoint arm, output torque or direct-current side voltage can be realized through certain compensation algorithm. According thereof provided by invention, stable, controlis simple; operate stably under state winding, high, reliability high.
