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 12):
The bypass frequency conversion control system according to  claim 11 , characterized in that it also comprises:\n a first switch, set up on the first power supply circuit and used to control whether the first power supply circuit can power and output the network voltage signal to a motor; a second switch, set up on the second power supply circuit and used to control whether the second power supply circuit can power and output the voltage signal output by the frequency converter to the motor; and a controller, used to connect the first switch and cut off the second switch when the switching instruction is received from the frequency converter.
