This invention provides a frequency converter and bypass frequency conversion control system, and its switching control method, belonging to the technical field of motor drive control. The frequency converter of this invention accesses a network voltage signal with a corresponding first frequency and first phase, wherein the frequency converter is configured to be able to operate in tracking and synchronization mode, and in tracking and synchronization mode, the frequency converter tracks the first frequency and first phase of the network voltage signal in order to basically synchronize the second frequency and second phase of its output voltage signal with the first frequency and corresponding first phase of the network voltage signal. The frequency converter of this invention achieves simple, low cost, fast synchronization with good synchronism.
