Abstract
A phase-loss control method for a three-phase three-wire converter and a three-phase AC control system are disclosed. The processor executes this method by receiving a power signal, determining if the power signal has a phase loss, and determining whether the power signal had the phase loss at the previous moment. If there was no phase loss at the previous moment, it switches from a second operating state to a first operating state, outputting a first drive signal. If there was a phase loss at the previous moment, it switches from the first operating state to the second operating state, outputting a second drive signal. By detecting phase loss, the system can immediately switch between the first and second operating states based on whether phase loss is present or not, without causing the three-phase converter to shut down. This method allows seamless state switching, improving system stability.
