| Abstract |
In this paper, a new method, cascade 3 phase IHCML(Isolated H-bridge Cascade Multi-Level) inverter and a control method is proposed by using two 3-phase transformers that have respectively different transformation rates. Vector control technique in which the highest proximity vector has been used is also put into use. With this process, the switching frequency is almost identical with the output fundamental frequency, which makes less switching loss, and the switching frequency of the small volume of the H-bridge that is in charge of small power is highly controlled, which improves the quality of the output voltage. |
