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 11):
A bypass frequency conversion control system, comprising a first power supply circuit and second power supply circuit arranged in parallel, wherein the first power supply circuit can power and output the network voltage signal to a motor, characterized in that it also comprises:\n the frequency converter according to  claim 1 , set up on the second power supply circuit, thereby enabling the second power supply circuit to power and output the voltage signal output by the frequency converter to the motor; wherein the frequency converter is also configured to: issue a switching instruction when it is determined that the second frequency and second phase of the output voltage signal are basically synchronized with the first frequency and first phase of the network voltage signal to achieve switching between the network voltage signal power output corresponding to the first power supply circuit and the voltage signal power output by the frequency converter corresponding to the second power supply circuit.
