Abstract：Modulation method of inverter with single polar modulation and double polar modulation, the traditional single polar modulation method is low switching loss, high efficiency, but the common-mode interference is more serious; and the double polar modulation is high switching loss, low efficiency, but can resist common-mode interference. This paper introduce a new modulation method, combines the advantages of the traditional single polar and double polar modulation methods, which not only can reduce the common-mode interference but also improve the efficiency of the inverter; inverter can be controlled the off-grid and on-grid operation status base on the new modulation method. The paper through simulation shows the advantage of modulation method and feasibility of this system.
