Abstract
A startup control method for a DC/DC converter is used for starting the DC/DC converter with energy transferred from a low-voltage side to a high-voltage side, and includes: acquiring a voltage spike measurement value of a power switch at the low-voltage side; determining a duty cycle or a frequency of a driving signal according to the voltage spike measurement value and a preset voltage; and outputting the driving signal to a power switch at the high-voltage side, thereby charging a clamping capacitor of the power switch at the low-voltage side. The startup control method for a DC/DC converter of the disclosure can improve a reverse charging power of the converter to the maximum extent and reduce the time needed for charging a bus capacitor during a reverse startup process while ensuring voltage stress on the power switch not to exceed a limit.
