Abstract :
The nonlinear phenomenon of APF is analyzed and so does the nonlinear problem caused by the instability of the gate drive voltage of IGBT. During the research, the problem can be changed into the transmission process analysis of the instant pulse current produced from the process of IGBT on-off, the refrain of structural stability problem which caused by IGBTpsila control voltage translated into interdiction of the spreading plus of the instant electric pulse or attenuation of spreading path, after the research of switching power supply in methods of simulation and test result. It is certain that flyback switching power supply can be used in the auxiliary switch power of APF and it will be useful for the active power filter to restrain the nonlinear problem.
