电压源变换器间谐波THD放大效应的概念与案例研究

In this letter, with the consideration of both PLL and the inter-harmonic voltage perturbation, a technical concept of “inter-harmonic total harmonic distortion (THD) amplification” has been presented, by which a hidden output feature of voltage source converter (VSC) has been unveiled. The phenomenon has been explained in theory that the THD of current is greater than the THD of voltage under the...
