Abstract
Disclosed are a voltage compensation method and device of a voltage reducing circuit. The voltage compensation method includes: determining a capacitance value of each capacitor and a resistance value of each resistor in a voltage compensation circuit according to a voltage compensation expectation of the voltage reducing circuit; determining each zero and each pole of a transfer function of the voltage compensation circuit according to the capacitance value of each capacitor and the resistance value of each resistor; setting each capacitor and the resistor not in direct connection with the capacitor in series to have a positive temperature coefficient, and setting the resistor in direct connection with the capacitor in series to have a negative temperature coefficient; and compensating voltage for the voltage reducing circuit by using the voltage compensation circuit to output a rated voltage.
