多电平单相级联有源滤波器载波调制与电容电压平衡方法
Carrier Modulation and Capacitor Voltage Balance Control of a Cascade Multi-level Single-phase Active Power Filter
摘要
Abstract
Recently,cascade converters are more widely used in high-voltage high-power fields.In this paper,an active power filter(APF)of cascade multi-level phase-shift single-phase voltage type is studied.At first,the inter-module carrier phase-shift control principle is analyzed.Then,a DC capacitor voltage balance control method is proposed.At last,a simulation model is built in Matlab platform.Simulation results show that the proposed cascade filter can effectively control the harmonic currents caused by load,and ensure the stable DC-side voltage of each module.关键词
