Embodiment Construction
[0036] An optimal control algorithm for pulse width modulation of a three-level neutral-point clamped converter for controlling neutral-point voltage balance, comprising the following steps:
[0037] ① Establish the mathematical model of the specific harmonic elimination control method for the three-level neutral point clamped converter.
[0038] The three-level single-phase voltage waveform satisfies 1 / 4 cycle symmetry. According to the Dirichlet theorem, the waveform can be decomposed into the following Fourier series:
[0039] U A N ( ω t ) = A 0 2 + Σ n = 1 ∞ [ A n s i n ( ...
