Variable frequency power supply

The working principle of frequency conversion power supply:

The variable frequency power supply uses electronic components to convert the input power into a high frequency AC power supply, and then depresses through the transformer to obtain the required output voltage and current. The core components of variable frequency power supply are resonant circuit and switching tube. Its working principle is mainly to control the switching tube's on-off and cutoff by changing the frequency and duty ratio of the modulation signal, so as to adjust the output voltage and current.
