Claim 2:
3. The isolation type power conversion method based on demagnetization iteration control according to claim 2, characterized in that
the turn-on time Ton of the primary side power tube calculated by the adaptive turn-on time control circuit according to the primary side bus voltage VIN parameter in Step 4 is:

Ton=C*V/(l/k*G*VIN),

wherein, VIN is primary side bus voltage of an input voltage bus located at the primary side of the high-frequency transformer;
C is a capacitance value of the first capacitor;
V is a voltage value of the first reference voltage source;
l/k is a voltage division coefficient of the voltage division circuit;
G is a transconductance value of the first voltage-controlled current source circuit.
