| Abstract: | Through studying complete mathematical module of LCL filter,a current loop control structure of PWM voltage source converter based on simplified module of the LCL filter is derived.The control structure does not reduce system performance,and can inhibit high frequency switching harmonics in the current and guarantee the current being stable and rapid response in a dynamic process.The simulation and prototype experimental result confirms that the simple control structure is correct and effective. |
