    • The invention relates to a power converter circuit (4), which comprises at least two submodules (24, 26) in a series circuit, which draws electrical power from a power source (8) outputting a DC voltage (18), via an inductance (22). Each submodule (24, 26) has, on the input side, a single-phase half bridge and, on the load side, a single-phase full bridge, and the half bridge and the full bridge are connected on the DC voltage side, and an intermediate circuit capacitor is connected in parallel therewith. In the power converter circuit specified, at least one electrical line comprising a plurality of current paths (42 to 46) connected in parallel with one another is formed in each submodule (24, 26).
    • 本发明涉及一种功率转换器电路(4),其包括串联电路中的至少两个子模块(24,26),所述子模块从输出DC电压(18)的电源(8)汲取电力,经由电感 (22)。 每个子模块(24,26)在输入侧具有单相半桥,并且在负载侧具有单相全桥,半桥和全桥在直流电压侧连接, 并联一个中间电路电容器。 在所述功率转换器电路中,在每个子模块(24,26)中形成至少一个电线,所述电线包括彼此并联连接的多个电流路径(42至46)。
