Voltage Waveform and Voltage Boost Ratio of Quasi Z Source DC Converters
Year: 2025
Type: article
Abstract: In order to optimize the voltage waveforms of quasi Z source converters and investigate their effects on voltage boost ratio, the LTspice software is used to conduct a simulation study on quasi Z source converters after theoretical analysis. The results indicate that: 1) Only by using large inductance values and employing a damping filtering method with capacitor and resistor in series can a good square waveform be obtained; 2) With a good voltage waveform obtained, the voltage boost ratio of quasi Z source converters is approximately equal to the theoretical value; 3) When the voltage waveform is distorted or incomplete, a higher voltage boost ratio can be achieved, but this voltage boost ratio is not desirable; 4) The above three conclusions are also applicable to Boost DC converters.
