Self-excited inverse process converter electronic circuit
The figure shows the electronic circuit diagram of the self-excited inverse process converter. The low power converter in this circuit converts the higher voltage from the main power system into another voltage required on the board. The operating frequency is 250kHz. ZI acts as an output voltage regulator and limits the drain voltage below the breakdown voltage of the VMOS.
