1. Introduces a novel alternate-arm multilevel converter (AAMC) topology with two key parts: conduction switch and shaping circuit
2. Proposes a strategy of using third harmonic current injection to achieve capacitor voltage balance
3. Establishes AAMC model on PSCAD/EMTDC platform and verifies the effectiveness of the proposed strategy
The article is generally reliable and trustworthy, as it provides detailed information about the novel alternate-arm multilevel converter (AAMC) topology, its advantages, and the proposed strategy of using third harmonic current injection to achieve capacitor voltage balance. The article also establishes an AAMC model on PSCAD/EMTDC platform and verifies the effectiveness of the proposed strategy.
However, there are some potential biases in the article that should be noted. For example, it does not explore any counterarguments or present both sides equally when discussing the advantages of AAMC topology. Additionally, there is no mention of possible risks associated with using this technology or any other potential drawbacks that should be considered before implementing it. Furthermore, there is no evidence provided for some of the claims made in the article such as “no circulating current” or “can handle DC faults” which could lead to readers being misled by these unsupported statements.
In conclusion, while overall reliable and trustworthy, this article has some potential biases that should be taken into consideration when reading it.
