Power converter, power adapter, electronic device, and power conversion method

A method for power conversion, comprising:

• detecting an output voltage of a conversion circuit to obtain a voltage value of a first voltage;
• generating a slope compensation signal based on the voltage value of the first voltage;
• obtaining an error signal based on an error between the voltage value of the first voltage and a voltage value of a reference voltage;
• comparing the slope compensation signal with the error signal to obtain a comparison signal;
• and
• generating a drive signal of the conversion circuit based on the comparison signal.

An electronic device comprising:

• a battery;
• a load;
• and
• a power converter comprising:
• a first conversion circuit;
• and
• a control apparatus connected to the first conversion circuit,
• wherein the control apparatus is configured to:
• detect an output voltage of the first conversion circuit to obtain a voltage value of a first voltage;
• generate a slope compensation signal based on the voltage value of the first voltage;
• obtain an error signal based on an error between the voltage value of the first voltage and a voltage value of a reference voltage;
• compare the slope compensation signal with the error signal to obtain a comparison signal;
• and
• generate a drive signal of the first conversion circuit based on the comparison signal, wherein the power converter is connected to the battery and configured to:
• convert an output voltage of the battery to obtain a target voltage;
• and
• output the target voltage to the load.
