Abstract

See full text

A method for controlling a dead time of a secondary side of a power converter includes giving a previous first turning-on time and a current first turning-on time corresponding to a primary side of the power converter, generating a first voltage and a second voltage according to the previous first turning-on time and the current first turning-on time, respectively, generating a current first target voltage according to the first voltage, the second voltage, and an ideal voltage corresponding to a previous ideal second turning-on time of the secondary side, and determining a current second turning-on time of the secondary side according to the current first target voltage and a first ramp voltage corresponding to a current ideal second turning-on time of the secondary side. A difference between the current second turning-on time and the current ideal second turning-on time is a current dead time.
