Structure Analysis of frequency converter. The Capacitor C and its associated DC bus are considered as the DC power supply. It can be found that the whole inverter takes capacitor C as the center of the symmetrical structure. If the impedance value of ACL is selected properly, then the vector control method of symmetric and equal can be applied to the AC motor with the main circuit of rectifier and inverter, thus constitutes the dual PWM AC drive system. DUAL PWM AC drive system makes it possible to carry out vector control on the secondary side reactance of transformer. What needs to be explained is that just like the inverter requires a special inverter motor, the PWM vector control rectifier also has corresponding technical performance requirements for the transformer. This paper only analyzes the principle of the rectifier, the corresponding technical changes of the transformer are not discussed. Special attention should be paid to the influence of the development of various types of optical fiber sensors (such as sensors for sensing physical quantities such as current, voltage, electric field, magnetic field and temperature) on the field of relay protection
