Abstract :
In order to suppress the switching harmonics in subsection synchronous modulation algorithm, two proposals, zero voltage switching half cycle and voltage phase compensation, are proposed. To verify the performance of the above two solutions, simulation circuit is built by PSIM software and then experiments are carried out on VVVF prototype based on DSP56F8346. Simulation and experimental results both confirm the effectiveness and practicality of the two solutions.
