Abstract
The disclosure provides a chain-link converter, comprising: a first node; a second node; and a plurality of switch submodules, wherein the plurality of switch submodules are connected in series, and the plurality of switch submodules are electrically connected between the first node and the second node, and a switching time of at least one switch submodule is greater than the switching time of other switch submodules. The chain-link converter of the disclosure effectively suppresses the common-mode current by extending the switching time of at least one switch submodule.
Claims24
A chain-link converter, comprising:
- a first node;
- a second node;
- and
- a plurality of switch submodules, wherein the plurality of switch submodules are connected in series, and the plurality of switch submodules are electrically connected between the first node and the second node, and a switching time of at least one switch submodule is greater than the switching time of other switch submodules.
A three-phase chain-link converter, comprising:
- a three-phase source;
- a high-frequency submodule;
- and
- a plurality of low-frequency submodules, wherein each phase of the three-phase chain-link converter comprises the plurality of low-frequency submodules connected in series, three phases of the three-phase chain-link converter share the same high-frequency submodule, and a switching time of at least one low-frequency submodule is greater than the switching time of other low-frequency submodules.
