High-power variable-frequency power supply output characteristics and experimental analysis

Abstract: The output characteristics of high-power variable-frequency power supply under various loads (including pure resistive load, inductive load, capacitive load, and nonlinear load) are analyzed. The experimental results show that the output voltage and frequency of the variable-frequency power supply are very stable under various loads.

As we all know, the mains frequency we use is 50Hz, but in real life, sometimes the power frequency required is not 50Hz, which requires a variable frequency power supply. For a power supply, users expect it to output a stable voltage under various loads, and variable frequency power supplies are no exception. Therefore, it is necessary to study the output characteristics of variable frequency power supplies under various loads (pure resistance, inductive, capacitive, nonlinear).
