The invention provides a novel rotating
rectifier with a fault monitoring function, and relates to rotating rectifying systems. The invention aims at solving the problems that an existing
rectifier is low in output power of an alternating-current
exciter and high in
harmonic component, a rotating rectifying controller cannot be timely started and a
system fault exists. The novel rotating
rectifier with the fault monitoring function comprises a three-phase triple
voltage rectifying circuit, an alternating-current
exciter, a rotating bridge rectifier module based on VIENNA, a start
power module, a start
resistor, a rotating rectifying controller, a synchronous electric
exciter set, a fault detection module, a
wireless communication device, a first
wireless transceiving device, a second
wireless transceiving device and an external monitoring module. According to the novel rotating rectifier with the fault monitoring function, a neutral-point potential balance method of injecting zero-sequence voltages is adopted, zero-sequence voltages VZ(+) and VZ(-) are injected into a three-phase reference
voltage at different moments, and the problem is solved that two
capacitor voltages of a
direct current busbar are not balanced.
