Three-phase Inverter Based on Three Harmonic Injection

Abstract

The fundamental principle of the three-phase inerter based on 3rd harmonic injection is introduced in this paper. The method of how to generate sine table include 3rd harmonic injection is detailed analyses in this paper. The detailed set of the register in the controller and the interrupt code are given. Detailed analyzed and calculated about the device choice were discussed. Simulation results and experimental results are given, which improve the correctness of the method.
