Abstract

This invention relates to a wide-range soft-switching SIDO Buck converter control method and apparatus. The method includes: at the start of any cycle, acquiring the converter output voltage Voa, output voltage Vob, input voltage Vin, and the average value of inductor current; and based on the output voltage Voa, input voltage Vin, and the average value of inductor current I... L The control circuit switches in the converter are turned on and off; based on the output voltage Vob, input voltage Vin, and average inductor current I... L This invention controls the on / off state of the main switching transistors in the converter. It offers the advantages of achieving ZVS (Zero-Voltage Switching) on ​​for all switching transistors and high efficiency.
