摘要: Aiming at the problem that low-order harmonics generated by EAST poloidal field power supply is difficult to control, a new method combining active filter and passive proposed. The topological structure filtering principle of low frequency suppression hybrid are described in detail. A three-level space voltage vector modulation algorithm for reducing fluctuation DC side midpoint introduced, calculating basic time given. Combined with algorithm, output simulated, feasibility scheme effectiveness design verified.
