A novel control method for single-phase power inverter systems based on Hilbert transform and DQ transform

Li Cui; Liu Zhenxing; Chai Li; Wang Jiying

In the control of 400Hz power inverter systems, a new method based on Hilbert transform and DQ transform is proposed. The αβ coordinate is structured according to actual measured voltage and its Hilbert transform. Then the DC quantities under the rotating coordinate is obtained by the DQ transform, followed which the double closed loop control model can be structured. Compared with the conventional method which the BETA data is structured by the 90° delay, the good performance of the proposed method is verified in the simulation results. In addition, on the circumstance of the sudden load adding to the system, the method eliminates the secondary subsidence of output voltage problems, which cannot be solved by the conventional 90° delay method.
