Abstract:
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.

Claim (Index 6):
The frequency converter according to  claim 2 , characterized in that the output voltage and frequency control module is also used to:\n compare the second frequency and first frequency in tracking and synchronization mode, and cause the second frequency and first frequency to tend toward synchronization when the absolute value of the difference between the second frequency and first frequency is greater than a first pre-set value, until the absolute value of the difference between the second frequency and first frequency is less than or equal to the first pre-set value.
