This paper presents a power quality evaluation of the Class-D high-frequency power amplifier/inverter. The real, reactive, complex, apparent, distortion, and non-active powers at the input of the ...

The frequency is how often a value occurs in an interval, while the distribution is the pattern of frequency of the variable. They are often depicted in a graph or table.

In this paper, a class of single-phase Z-source (ZS) ac-ac converters is proposed with high-frequency transformer (HFT) isolation. The proposed HFT isolated (HFTI) ZS ac-ac converters possess all the ...
