Hybrid I-T type multi-level converters

A multi-level converter includes a plurality of capacitors coupled in series between first and second nodes of a DC port and coupled to one another at n-2 first intermediate nodes. The converter alsoincludes a switching circuit including at least one first switch configured to couple the first node of the DC port to an input/output node, at least one second switch configured to couple the secondnode of the DC port to the input/output node, and at least three third switches configured to couple respective ones of the first intermediate nodes to the input/output node. The converter further includes a control circuit configured to control the first, second and third switches to provide an n-level converter. 一种多电平转换器包括多个电容器，该多个电容器串联耦接在DC端口的第一节点与第二节点之间并且在n-2个第一中间节点处彼此耦接。该转换器还包括开关电路，该开关电路包括：至少一个第一开关，该至少一个第一开关被配置为将DC端口的第一节点耦接到输入/输出节点；至少一个第二开关，该至少一个第二开关被配置为将DC端口的第二节点耦接到输入/输出节点；和至少三个第三开关，该至少三个第三开关被配置为将第一中间节点中的相应节点耦接到输入/输出节点。该转换器还包括控制电路，该控制电路被配置为控制第一开关、第二开关和第三开关以提供n电平转换器。
